Using battery power to go off the City's power grid


I'm using a Bluetti AC200MAX 2,200 watt expandable power station to take my system off the city's power grid.  It runs off a lithium ion phosphate battery with a 4,800 watt pure sine wave inverter. My total system only takes about 450 watts so I have never heard the fan kick on - it is totally silent. The music comes from a completely black background, with a huge soundstage that sounds very natural. I know that Ric Schultz has talked about these types of setups and there is a very expensive Stromtank battery system that is marketed to audiophiles. Anyone else tried this type of setup in their audio system?

Here is a link to a review:

You want to know how a 2200 watter sounds versus the 5000 watter?.....you buy them both and compare.....You have the credit to do that ($1300)?  or are you as money poor as me? (remembering that you can get your money back on either or both).

"If you can’t agree to that please move on." So we have to agree to what you want? or we have to leave? U da boss?

I am all for measurements....they are great....I like numbers. Do they mean anything sonically?.....sometimes they do.....sometimes they don’t. Please measure Inverters any way you like and maybe some measurements will correlate to what we hear.....then we can all learn something.

However, to know what something "sounds like" you have to listen.........Listening is numero uno....everything else is secondary.

Noise and distortion are the same thing.  When you reduce noise then you hear more of the true musical nature of the instrument....you hear more harmonics, you hear more nuance, you hear more space around the instrument, you hear more body to the instrument.....It is all about noise.  YOU can have lower overall noise and yet the bass could be looser because the output impedance of the amp or inverter or whatever is too high.  Many factors are independant.....not everything is "more detail".....in fact, a pushed upper midrange can increase apparent detail but is actually phony.  A lot of silver wires and connectors do this....I have tested this via straight wire bypass tests.  When certain types of noise go away the hardness goes away.....this can be disconcerting to those that like zippy sound.....or are used to a certain amount of "speed" being present.  An acoustic guitar played normally does not have speed.....I play one,.......now if you bang on it.....that is another story.  I used to play the Chesky CD.....of Livingston Taylor....titled INK......I used to think the guitars were maybe electric because they were so zippy.....over the years my stereo has got more refined and now I hear the guitars so clearly.....as acoustic instruments in their own space........the inverter helps with this. 

The Bluetti is in my room.  I will be testing it tomorrow.....pretty sure it will have much better bass than the tiny Goal Zero......we shall see.  I am only testing it on the power amp as my front end is hardwired into the Goal Zero.....the amp was being plugged into it.....So, just the amp will be run off the Bluetti while the Goal Zero will still power my transport and DAC.

When I ask my friend if he is done with his stereo.....he always comes back with "well if I can reduce the noise further.....I am in"......this is why he keeps improving his stereo......He just got the upgraded power cord from Puritan that runs from the inverter to the Puritan.....he said it "lowered the noise" even further so now everything is slightly better.  Next, he has the new Puritan Route Master coming.....When he changed his wire from his ground rod from 14 or 12 gauge to 4 gauge it lowered the noise mucho......this game never ends....people who say...."I don't hear any noise from my stereo....it is dead quiet"......have no idea what I am talking about.  This is not hiss or audible noise......this is low level noise that is obscuring the signal at low levels and it affects the sound in serious ways.  You go "I did not know there were 4 back up singers....I thought there were 3......now I hear what brand of strings are being used.  Now, I hear everything laid bare like never before"......again this is not hiss or normal noise you would hear from the speaker when you lift the needle or put your digital on pause.....

Low level noise is everywhere....this is why you want great cables, cables off the floor, great AC, remove as many connectors as possible, use my Music Purifiers and Ground Enhancers, use super contact cleaners, super stands and feet, remove or use audiophile fuses, felt around mids and tweets........time align your speakers, use the best caps, coils, wire and resistors in the speaker xover, use Bybee Clarifier on the back of the magnet, hardwire the xover right to the voice coil wire on drivers, etc. etc. etc. into infinity.  Everything has noise.....so removing as many things as possible helps and what is left....you got to scrub it clean.  It is not about dry super detailed sound.  It is about super natural super detailed OMG I am crying and goosebumps sound.  When my friend went from his Ecoflo Pro to the Gaindel.....he was besides himself......he said "It's like the person is playing for ME......I can hear exactly his intentions and inflections.....it is so real"......I think, many of use are seeking this experience.  Now his system is at least $80-$90K......but he cannot stop......it just keeps getting so much better.  My whole system......I mean everything is about $5500.......but becaue it is so simple and pure.....OMG, does it sound good.  Every part needs to be "noise lowered".....tweaked to the max....or you are missing a lot.  EVERYTHING MATTERS......Worship everything and everyone.....It is all divine.  The noise in our minds.....is ego chatter.....when we reduce that noise then we feel more love, joy, peace and compassion......we FEEL more alive.......every single second is the most incredible moment that has ever happened in the entire history of the entire cosmos.........the miracle of NOW.......is awaiting on you all.......wake up and breath in the joy and love with every breath.....you are loved, you are blessed and you are deserving........This has ALWAYS been so.

You can ground an inverter to any true ground point......like the third pin in your wall....There are some really old buildings that have no true ground....this is certainly not to code and probably illegal.  I lived in a building like that in Berkeley back in the 80s.....I had to put a clamp on the cold water pipe to ground my system.

Viber and anyone/everyone else,

Why don’t you become the Inverter tester for the world. Buy the Bluetti, buy a 2000 watt Giandel, buy the 5000 watt Giandel and a couple of the 200 amp hour batteries.and a charger and OFC battery cables.....and do the tests on your system and let everyone in the world know......you can try the stock versus OFC cables, one versus two batteries....footers under the inverter, etc.

You can afford it. I bet you have that much on a credit card (maybe $4500 total?). Whatever you do not like, you return for a refund. I would do this.....but I have no credit/money......You have money....you can do this. Why are we always waiting for someone else to do things for us?......It’s way more fun to be on the leading edge.....be an explorer....have some fun.

The Bluetti does not give you access to full power on any outlet. The Giandel has a terminal block that you can hook up a Furutech outlet to, a power strip to or hardwire a cable or whatever for full output. The Giandel also allows unlimited power upgrades (as much battery as you want) and can use whatever battery you like including just trying it with a car battery......way more flexible.

Of course you can start small (for the toe dabblers).......just buy a 2000 watt Giandel for a lttle over $300 and hook it up to a car battery......if you like that then buy the 5000 watt Giandel and if that sounds better than return the 2000 watter......then get a single 200 amp hour LifePo4 battery and compare to your car battery......then try another battery......etc.......come on.....you know you want to try this.....yes, you do.

Viber,

I never said the larger Giandel is better in any way than a smaller one. Show me where I said that? Do you just make stuff up? The larger one can do more current (which most people do not need) and will turn on its fan at higher power. No one has A/Bed inverters that I know of except my friend who said the Ecoflow Pro beat the Goal Zero Yeti 3000 and both where trounced big time by the 5000 watt Giandel. That is all I know. We are in new territory here.....this is why I suggested you or someone buy both the large and small Giandel, the Bluetti and have a comparison party. You could A/B cheaper heavy AGM batteries with LifePo4 batteries, as well.

NO ONE KNOWS ANYTHING. How many brands of power amp are there? They all sound different.....How many brands of inverters are there? They all sound different. I personally would go for the Giandel because my friend (who has an $80K super revealing tweako system using super modified Apogee speakers) is the one that tested the inverters......he has great ears.....even listens to symphonies.....and jazz and pop and opera and rock and oldies, etc. Has both super vinyl system using Lithuanian field coil cartridge and r to r DAC.......every part in his system selected for sound.....and a very good room.

Yup....just buy a good three prong plug and put a large guage wire (12 gauge is fine) into the third pin only.....plug it into your strip or the wall and.....attach the other end of the wire to the inverter.  Any hardware store will have the plug and sell house wire by the foot....stranded wire is way easier to work with.

What is theaudioamp man about? Do you want people to get better sound? What is your shtick? What components have you heard recently that have made your stereo sound better? Will you help us? Do you want to help us? I (and some others here) want better sound....what do you want?

Viber,

You are a rehasher......you restate what others say but add your own "color commentary". You quote me above and then you rehash it again....but again you cannot get it right. I did not say "a larger inverter would sound better" What I said was ’I would think......and probably"..... Maybe you cannot read? Or do you just like drama? Again, I don’t know nothing. Does a larger inverter have lower output impedance? I do not know. Does a larger inverter have a larger power supply? I would GUESS it would. Stop making things up!

You can buy cheap AGM battery to try (with refund capability). You can buy Renogy LifePo4 batteries through Home Depot.....and I (THINK....MAYBE...YOU BETTER CHECK) they have return policy......you can build your own LifePo4 batteries real cheap......lots of alternatives.....if you really just want to dip you toes in the water.

Guys.......regenerators and balanced power compared to a great sounding inverter is like racing a model T against a Tesla.  But you will have to try the 5000 watt Giandel to know.  You know nothing without listening.  You have invested in the past.....now it is time to listen to the future.......which is now.....always now.  What you did before does not make it great NOW.

This is what you said.....direct quote

"No ricevs, all inverters do not sound different unless you have poor equipment. Some people believe that everything sounds different and are more open to suggestion. Other people are more skeptical and realistic. Actually I do know how a Powerwall Inverter sounds. It sounds just like the AC line, which sounds like exactly nothing in my system."

So, what are you doing on this thread if you feel that inverters are worthless and that your wall AC sounds like "nothing"? What is your purpose here?

You assume a lot.  You have a fixed idea how things work.....However, your "point of view" does not help anyone get better sound. You just expound "science" in an effort to feel better about yourself. You are already glorious.....you do not need to "try" to show us how wonderful you are.....you are truly loved.....because you are worthy and deserving.....just like everyone else on the planet.

So, who is going to be the second to try the 5000 watt Gaindel system and get back to us?

Again, you will not answer my question......What are you doing on this thread? What is your mission here? To save us all from spending money on Inverters we do not need? We do not need SAVING......We listen on our own and buy the stuff that WE feel makes our stereo better sounding......

You are looking for drama.....if you went to ASR and started saying all this they would just rool their eyes and say...."Well, of course, we already know all that.....you are boring......why don’t you go over to Audiogon where all those subjectivists are and you can really stir the pot there"........and here you are.....just stirring away....every chance you get.

What you think of as an "attack" is simply holding the mirror up to you.

You reported that you heard no difference between the powerwall and the wall AC......and you also stated that all inverters sound the same. Anotherwords, you have contributed nothing. How does what you say help anyone get better sound? I have also listened to an inverter.......I am using a Goal Zero Yeti 400 on my system right now and it improves the sound......but since my friend had a Goal Zero and then went to the better sounding Ecoflo Pro and then to the way, way, way better sounding Giandel system.....I know my Goal Zero is yesterdays paper.

What really matters is when others try the Giandel system and report back.....Nothing you or I SAY can improve the sound of someones stereo......but what I shared might certainly lead to that, if someone trys it. What do you recommend for better sounding AC? Nothing? It is all perfect?

When you say "help others to understand how audio works".......this is all in context to your belief that it is nothing but measurements are meaningful. What really matters is how something sounds. Can you help them get better sound? Or just tell them how it works.....according to your belief?

Audio, for me is not about belief......it is about BE and LIVE. You experience sound.....you experiene music......it is not about some opionion of what matters or does not matter.......the ear KNOWS.....the heart KNOWS.......the small brain just thinks it knows......but it really knows nothing of significance, if it is not open to BE and LIVE.......Do you think joy and love and peace and beauty? Yes, thoughts of these can leade to those states.......but really what you want to do is to FEEL joy and love and peace and beauty. Will you let yourself FEEL? As the saying goes......Would you rather be right.....or LOVING? You choose, every second.

"I'm so glad, I'm so glad, I'm glad, I'm glad, I'm glad."  Please sing along!

Choose your reality........you do it every second.  Do you want to be glad?  if so, choose it now......right now.  Do you want to be right?  Then choose it right now.

Would you rather be Loving or Right?  You choose.

Being right is blah, blah, blah (it's whats called a Blah life)......being loving is happiness, joy and sharing.

theaudioamp......yes, I would say you have an agenda and a need for attention and it interferes with your ability to know truth (how something sounds)....just a wild guess.

The only thing TRUE in audio is how something sounds.......audio....means sound........measurements are squiggles on a scope.....they are not audio. In order to know the Truth about audio....you need to do serious listening tests (and they do not need to be blind or double blind......unless you are double deaf). You can trust your hearing.....you can trust your memory.....we are pretty amazing. You have to trust yourself. If you only trust a test instrument.....that is sad.

 

"If you have cancer go for the loving doctor"

So, you want your doctor to be unloving? I had three cardiologists....and the only one that figured out what was really wrong was the super loving one. Love does not mean lack of science......love means you care enough about the person that you look deeper because you CARE. Thank God for this loving doctor......I might not even be here now, if he did not care so much.

I would say 98 percent of the threads and interactions on this forum are subjective based......very little talk of measurements, except when an objectivist drops in to stir the pot.......or a product is discussed that was reviewed on ASR.....etc. So, what is an objectivist doing on this forum? Hardly anyone cares about graphs and blah blah. You certainly cannot have a discussion with an objectivist about what sounds good. It is like a atheist walking into a church and waving a science book in the air and talking real loud about how there is no God as it cannot be measured and proved via science. What purpose is this behavior? Does it make anyone happy? This behavior is NOT loving. Love gives people what they want.....not what you want. People here want better sound. Got any of that? What and who are you glorifying? Life is incredible......we are all beautiful.....may we all see and feel our own worth and beauty.

Let's do the "Summer of Love"  forever!!!!!!

Remember the Troggs?....."Love is all around us".....check it out on Youtube.

Arguing and winning is what the ego does. How are you helping anyone by your words? Love does not care about winning.....Love simply cares about everyone.

When I was in jr. college I took a class called "marriage and family"......The very first thing the teacher did was to draw a six foot line on the chalkboard....and at the left end he wrote "ego"......on the right end he wrote "agape"......He turned around and said that the further we were to the right on this graph the more happy we would be and the more happy others would be.....I about fell off my chair. This is the bottom line......we choose to live somewhere on that line every moment. The evolution of the soul is just that.......moving to the right......or if you made the line vertical....moving upwards to the light (ever raising our vibration). We are all so blessed. We are the very light ourselves.....the light of light....share it freely with everyone.

 

Guys,

There is no use in trying to reason, fight or argue with an objectivist. Their whole reason for existence is to argue and be right......so they will never give in....and they always have to keep arguing and have the last statement. So, just let it lie.....because it takes two to tango.....and that is what he wants.....he wants a fight. So, put your swords away because you cannot win against an objectivist......even though someone "scoring" the "fight" from a distance may give you every round.....it does not matter to him.....he will just keep saying he won. But winning and losing are the job of the ego......so if you are trying to win against someone who will never "say uncle’ then you are in your ego as much as him. All arguing does is make your own ego bigger......is this what you want? Just state the truth and let it lie. If you need to also clarify some point so his "nonesense" is not seen on its own as "truth" then do that but then STOP responding after that. I am done with him......nothing more needs to be said from me about what he thinks.

IT IS DONE........let him have the last word.

I surrender to the love of God.....flowing through my life.

Be Happy.........choose it now.

I don’t know what he does but it makes no sense (to me...at this moment) what the manual says.....as long as the inverter can handle the surge of the component....then why would it matter which way you turn it on? I believe he leaves the inverter on all the time and turns his amps on and off via the amps.....his JC1+ amps have delayed start up using relays. I believe he leaves all his low level components on all the time....except maybe his 300B based preamp (got to conserve those expensive tubes). He leaves the charger plugged in and running except when listening......so he is always at full battery charge when he starts to listen.

I don’t know what you are talking about when you say "2 to three times your power needs". The inverter only supplies what it is asked. As long as the inverter is large enough, it will work. Now about sound....it could be a way larger than needed inverter will sound better....same with paralleling batteries......these things need to be sonically tested.

You need to have an inverter that will handle the SURGE turn on current of your gear. For instance, my 400 watt Goal Zero will NOT turn on my Purifi Class D amp that only draws 30 watts when idling......because the turn on surge of the power supply in the amp is way above the surge capability of the Goal Zero.....the Goal Zero shuts off when I try to turn on the amp......so, I have an AC switch on my amp that switches between the wall AC and the inverter AC. So, I turn on the amp with the wall AC and then I switch to the Goal Zero power. If I had a 1000 watt Inverter I am sure it could handle the turn on surge. Why would anyone buy an inverter less than 2000 watts (4000 watt surge)?.....They are sooooo cheap ($350 for a Giandel).

If the battery charger is say 500 watts then the batteries will always be fully charged even if you have your low level components on all the time. Nobody has low level components that draw 500 watts......so just keep the charger on and connected to the battery and when you listen then disconnect the charger from the battery. Come on......this is simple! You do not need to turn anything off.....except maybe your power amp/amps.  Who cares how hot the charger is (they typially are switch mode so they run cool)?  As long as it is rated at 500 watts continuous (or whatever)....it should be able to do it all the time.

No matter how you use LifePo4 batteries.....they will last at least 10 years......by that time there will be batteries that have 4 times the capacity, last 30 years, weigh practically nothing and cost practically nothing.....anotherwords, find something else to worry about.  JUST DO IT!!!!!!

The batteries/BMS can handle 200 amps charging and discharging......He is charging with 40 amps and is discharging at 60 amps max.......so they may rise a degree or so....stop worrying.....JUST DO IT!!!!!

This is not a car.....in a car you need the most watts per lb.(energy density).....so LIthium Ion batteries are used.....however, they are not as safe as Lithium Polymer (LifePo4)......In our homes we use LifePo4 because they are generally safer. What the car industry is looking for is even more energy density and even lighter and more safe.....they will get there.....then we can use these batteries with our inverter.

LifePo4 batteries are already very energy dense......a 200 amp hour AGM battery is typically 125 lbs......A 200 amp hour LIfePo4 battery is 49 lbs.  The AGM battery is less than half the price.....but you cannot use all of its capacity and they only last less than half as long......They will actually cost you more over time and perform less good.  LifePo4 is pretty darn good (for now)

Maybe you will come up with some other concern......My sweet child.....I will hold your hand as we cross the street....You will be safe.

This is one of the problems with all in ones.....the fan noise. The probably better sounding Giandel Inverters won’t kick in the fan until 40% of the rated power is being used CONTINUOSLY. Having the batteries crammed right next to the inverter and the whole thing covered with a plastic cover.....means heat, heat, heat. The separate Inverters are all heatsink......and you can add as much battery as you like. The all in ones are prettier and you can carry them around and use them outdoors, etc. The separate inverter/battery systems are more than likely better sounding and way more powerful. Certainly the Giandel 5000 is clearly sonically superior to the Ecoflo Pro and the Goal Zero Yeti 3000. I would not touch another all in one.....I use the Goal Zero Yeti 400 becuase it cost practically nothing (less than $400 delivered) and I have no money for something better. I removed its plastic case so the fan will not come on.......my usual Frankenstein mod.....he he.

Ckearthink is a little cloudy today. We don’t use inverters because the US AC is so bad.....all AC is bad....anywhere in the world. Inverters in Switzerland will make the same SONIC improvement. We use inverters because is sounds better. We use Puritan line filters because it sounds better.....we use separate filtered ground rod and grounding for our stereo because it sounds better......this is the reason to be an audiophile.....to continuously enjoy making our stereos sound more and more alive and therefore we FEEL more alive.

You only need as much battery as you need. I am running my whole system on a 33 amp hour battery. However, my current draw with my CD transport, DAC and amp is only 45 watts.........so I get a few hours of liitsening before I need to charge.....However, it is not known what batteries do to the sound and how much battery sounds best.....this is a new game.....only a few are currently playing. Do LIfePo4 batteries sound better than AGM? If you use more battery than you need will it sound better as more batteries equals lower impedance from the battery? And since all inverters will sound different.....which brand sounds the best? And does a 2200 watt Giandel sound the same as the 5000 watter? NO ONE KNOWS any of this until more experiments are done. If you go to Audio Asylum on the tweaks forum you will see a thread I started about inverters. One guy bought the Giandel 5000 and is enjoying it. He has multiple class A amps so he wanted lots of battery. He ended up buying 2 200 amp hour AGM batteries.....AGM batteries cost half as much.....however, they last less than half as long......and a 200 amp hour AGM battery weighs 125lb.......A 200 amp hour LifePo4 battery weighs less than 50 lbs. So, if he bought LifePo4 batteries would it sound better? It will certainly be better on his back.

I I had the money i would buy the 5000 watt Giandel ($900) and a single 100 amp hour LIfePo4 battery ($400 and weighs 25 lbs.)......I am going to talk to the owner of the property here and see if I can install my own ground rod right outside my studio. By the way, a fully charged 12V battery is actually 12.6 volts or more. This is why a 200 amp hour batterey is rated at 2500 amp hours (12.6 X 200 = 2520). So a single 100 amp hour battery is 1260 watt hours.

When using you don’t get all the watt hours...you do not want to go below 10% charge on the low side for longest life. It is best to consider 80% when using. So if you have 5000 amp hours of battery.....think 4000 watts of actual use.

My friend with the Giandel 5000 watt system is running Apogee speakers and JC-1+ amps. When he had an amp that did ONLY 400 watts into 4 ohms the amp would clip when he would play Live At Leeds real loud......not now with the JC-1+s....he plays as loud as he wants. The Giandel says it is drawing around 650 watts with his whole system playing music......probably two to three times on peaks when rocking out. No problem with two 200 amp hour batteries.....gives him hours of play time without charging.......and if you have a very large charger you can charge Lifepo4 batteries up to 200 AMPS.....He hs a 40 amp (500 watt hours) charger and is fine. He plays for 3 hours and hooks the charger back up and in 4 hours is back to full charge....pretty fricking simple.

Yes, there are a few insane amps that idle at 1000 watts....but these are rare. Even the biggest monster D’Agostino amps idle at 480 watts each. 4000 watts class A?....who has that?

Most people could get away with a single 200 amp hour battery (2500 watt hours)......that is $800 and the Inverter is $900....a 40 amp charger is $250.........My system only draws 50 watts (class D amp)......and I am running a single 33 amp hour battery and am fine. A single 100 amp hour battery is $400.....half that much for an AGM/lead acid battery. But why would you want an AGM/lead acid battery that costs hafl as much as a Lifepo4 but only lasts half as long, is more dangerous, and weighs more than twice as much? The only thing you get is less cost outlay in the beginning. Just get a Lifepo4 and be done......and what is nice about a separate inverter is that you can add as many batteries as you like......and the Giandel sounds better than Ecoflo Pro and Goal Zero Yeti 3000 and PROBABLY Bluetti, etc. etc.

The owner of the property I live on has a Bluetti AC300 that is about 25 feet from me right now......so, he is going to bring it in sometime soon and I will a/b with my Goal Zero Yeti 400. The only thing the Goal Zero does negative is that the bass is not as good as the wall AC (when I run the amp on it). This makes sense as the output impedance of such a small inverter is not very low. If the Bluetti sounds in the league with the Goal Zero but has better bass....that is nice. However, my friend with the Giandel system first started with a Goal Zero Yeti 3000 which was sonically surpassed by the EcoFlo pro......which was then completely blown away by the Gaindel 5000/2 200 amp hour LIfePo4 system he has now. My guess is that any all in one will not perform at the level of a great separate inverter.......we shall see....errr hear.

BTW.....the PS Audio Regenerators do not use an inverter......they take the AC wall power and convert it to DC just like any power amp....and then create a sine wave and amplify the sine wave with an AMPLIFIER.......same as any amp running on AC..

Purepower regenerators do use an inverter.......but run off the wall AC......they convert to DC and then back to AC via the inverter.......PS Audio uses a power amp.

There are no specs for any inverters output impedance.....don't make stuff up...,..just listen and report what you hear......this is what we all want....real knowledge.

Viber,

The bass using the Goal Zero Yeti 400 is looser but not fuller...there is the same exact amount of bass as with the wall. It has relatively high output impedance compared to big inverters so makes sense that bass would be affected negativiely (sounds slower). You seem to have one opinion of everything....."something is either detailed, tight and accurate or its loose bloated and slow". This is far, far from the truth of things. There are a million shades of grey and many sonic factors are independent of each other. You can have loose bass that is less, the same or more than tight bass.....tight bass can be small, medium or large and full....yes, listen to some bass playing live......depending on the room, instrument, whether it is amplified or not....bass can have infintie descriptions. IT IS NOT ONE WAY......expand your mind.......it it infinite.....However, we ARE ONE......but many are the ways and names.

The Bluetti I have here is the AC200P not the AC 300 which is an inverter with out battery......this one has the battery.

OK, used the Bluetti on the amp (that draws 35 watts at idle).........the bass was a little better than the Goal Zero but the imaging was not nearly as real.....you can see the space of the recording venue and each instrument is in its own space more with the Goal Zero......The Goal Zero sounds a little soft......the Bluetti sounds more like the zippy wall sound. When listening with the Goal Zero you want to turn it up 2 db and then it is goosebump heaven. time The Bluetti is sitting on the floor and the Goal Zero up on some wood blocks. The Goal Zero also has a PPT AC thangy plugged into its spare AC outlet. Really the test is mostly meaningless. By having the amp plugged into the Goal Zero you are getting more noise interaction from the amp to the other components.....so, I should have a second Goal Zero just for the amp to be fair....and also a PPT thang plugged into the Bluetti and also have it off the floor.....everything makes a difference.....But, I will say I did not want to go back to the Bluetti after hearing the Goal Zero again......If this baby denuded Goal Zero sounds this good what the heck does a 5000 watt Giandell sound like? I want to know.....Maybe I will start a go fund me page and you guys can buy me one.....he he.

I use the Yeti 400 for the whole system...the front end components are hardwired into the inverter and I plug the power amp into it with a connector.......that is why I could not do the full system on both.  Who would A/B a $400 all in one with a $2800 giant Gaindel system?  No one.  As I have stated over and over again.......the Yeti 3000 was beaten by the Ecoflow Pro which was annihilated by the Gaindel system.  I have no idea how the Yeti 400 compares and who cares.....it is too small to use for most people and has a noisey fan (which I made silent by removing most all the casing).  My friend uses the Giandel sytem and used the Yeti and Ecoflow on his entire system.  Get out of your head!!!!  Just do it!!!!!

The Entech will tell you something but not much.  People are already modding the Puritan 156 (which would not even measure with the Entech). and getting better sound (and that better sound has NOTHING to do with a measurement).  We are talking better jacks, better wires and Fo-Q treatment.  I will be installing burned in Furutech outlets and inlet and better wire on my friends Puritan 156 next Wed.  Most things that make for better sound CANNOT be measured.  An inverter that measures lower with the Entech may sound way worse than one that measures better......this game is complicated.

Again with the clarity/resolution verus warmer/rolled off addiction game. It is not one game....It is not one way.....

You will only know what better is by trying one and listening......then you will know.. I can tell you a bunch of words (you like words) but words are not experience. When you get your Giandel (maybe in few years of talking about something you know nothing about).....and you listen.....ONLY then will you know what "better" is......but then again, you might find it "worse".....and this is why you need such hand holding.........."That jump off the curb really is small" says your mother....."I will even hold your hand." God, life, your mother, all of us are holding your hand. You will be safe. Trust the universe....trust your experience....but in order to have experience.....you have to JUMP!

So when is your Giandel arriving so you can listen and tell everyone what you hear? Or, are you just going to keep asking questions and making comments? Do you really want to know something? Knowledge is experience. I can describe the taste of chocolate all day long and you would still know nothing......You put a small piece in your mouth and you instantly KNOW..

Here are some words you all might like: The guy Oeno is the guy with the Giandel system....please read his comments: especially posts #56 and #61 on the next page

Viber,

I have never heard a Giandel Inverter.....I KNOW nothing about how is sounds......but I trust my friend and know his system (which is incredible). Here is what I will tell you......the Giandel will give you everything you ever wanted and more........or it won’t. he he

The PS Audio uses a generated sine wave and a power amp to do inversion....very different from the "normal" inverters. I don’t know the technology.....but looking at the schematics it is very different from a "normal amplifier". Actually, it does not matter about terminology.....of what does what.....What matters is the sound. Even Jay on his forum likes his $27,000 Stromtank inverter better than the $10,000 PS Audio thang (whatever you want to call it).

The quality of the inverter is based on infinte things. When I was modding the Exeltech inverters back in the 90s.....I changed the output filter cap from a Panasonic cap to a Wonder cap and the sound was more pure.....a gazillion things make for sound differences. The inverters out there are not made by audiophiles who listen to every resistor, wire, inductor, cap, damping, etc. etc. They are made to function well for their intended use......So, if you find one that is exceptional sounding for audo....it is a find......The Giandel seems to be the one for NOW.....only NOW....for tomorrow it may be tossed out for the SUPER DUPER lastest one......This game has just begun.

"My musical experience and knowledge exceed anyone you have ever met in your long life" Wow, someones ego is out of control. How do you know this? And WHY would you state that? Do you want to be seen as super important and all knowledgable? When you really love yourself deeply.....you also deeply love everyone. You would never try to make your self superior to others.....We know who is most loving....by their love. No one needs to brag that they are loving.

You are so beautiful.....you never need to brag or put on a display....you simply be yourself.....and the "yourself" that is real wants to always be of service and love everyone because that is what is REAL and gives the most happiness to everyone.

"I’ve learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel.”~ Maya Angelou

Please, love one another.....make someone FEEL good.

A beautiful woman was talking to me as I was leaving the property here a couple of days ago. She called me "sweetheart".........As I drove out in the street, I was glowing.....I kept saying to my self....."she called me sweetheart".........she made me feel good. So, my sweethearts....have a great day, and a great life...YOU are loved.....pass it on.

First paragraph.......Do you really think I am that stupid that I did not already know all that? Do you really think that would be easy to do and something I would want to do? Most of what you "mention" is already known....you like to reiterate things over and over and make it seem like you are super knowledgeable. But now I see why you want me to do it.....because:

In the next two paragraphs......you show your huge fear of loss. Look at the words you use....."I am prudent, minefield, financial ruin, don’t count on money back, tough economy, lose all money spent". Such drama!!!! You don’t trust the universe....This is sad. I feel sorry for you. If I had the money a Gaindel 5000 would be here in a minute.

You cannot take your money with you to the other side. Your life can be over in a millisecond. You can enjoy better sound or whatever you want in this NOW.....you can enjoy your life NOW. There is only the NOW.....ALL the love and joy and happiness that has ever existed.....exists right NOW. Most people are asleep to how alive and loved they are. Please wake up and enjoy the beauty that you are, everyone is, and the possiblilies of what you can do with your stereo and every other part of your life. YOU ARE LOVED. YOU CAN let go of your fear of loss.....the Universe LOVES you. Stereo is not really that important in the scheme of things.....but if you put energy into it....why not make it bliss and fun and play.......It does not have to be a struggle to "avoid financial ruin".........lighten up.....hug yourself....hug someone today.....go make someone feel good. Buy an inverter.....have fun! I AM Listening to the words I write. Truth applies to everyone....including me. I WILL be more trusting today. For I AM LOVED....I AM DESERVING.

I love words....I just now looked at the word deserving.......DE (of or about) SERVING.   When you feel loved....you feel grateful and you naturally want to give it to everyone......you want to SERVE.

Cool little toy.  The Puritan is so low in noise that it won't even measure on that thing......but a single measurement does not mean that much by itself.  I am going to change the outlets and inlet and wire on my friends Puritan on Wed. because people have already done this and said it "sounded better"......the different jacks and wire will not make it measure any different......most things that make for better sound cannot be measured.  You could have two inverters that measure quite similarly but sound radiclally different.
