The revolution has begun!

I have the Peachtree GaN 400...400 watt GaNfet amp. For $2500 there is no amp near it...a/b or Gan that is as smooth and musical. More so than my famed 845 tube amp. Must be paired with tube preamp ( Audio-gd). My LSR+ Maggies sing like a 5K-10K speaker. Sorry class A/ B fans. This is the way to get more of a Musical...pure sound and not at all etched. A/B is more etched and bright than a good quality GanFet. The AGD at 10 K is the best GAN amp but the GaN 400 isn’t far behind for 1/4 the cost. Try to find one used. Impossible.

" It changes PCM to PWM in software and then drives a GaN based class D output stage."  So, only PCM? Can't just take in the more analog sounding (your mileage may vary) DSD and be done with it? 

And if it can drive a GaN based class D output stage, why can't it just as well drive a class A or class AB output stage? Curious. 

@ricevs For me, the review I posted above said it all. Yes he was impressed with the sound given the price point of the amp. But the final word was it doesn’t produce the sound of amps costing 5 or 10 times as much. If $3000 is your budget for an amp, then the Class D is a viable option. But....... it's not the be all and end all to amplificatioin. Glad you are so happy with your equipment. Now time to let other be happy with theirs? Cheers.

I would love to know what xover, digital amps, power supplies and speaker drivers you use......this is very rare. I had a friend a long time ago that used the Panasonic receivers that had digital amps in them in a multi-amp system.......yes, correct....not new....but NOT very known. I know of no commercial speaker system in the world that is multi-amped with digital amps......you are just one of a handful of people around the world. After I spread the news to the whole planet.....he he....there will be many who will try this and laugh and cry with glee with the results.....and for very little (relatively) money put out.

People....wake up. This is not a normal class D amp like the Orchard, or Purifi, or Ncore, or Ice or AGD or Atmasphere or Merrill or Pascal, etc. This is a digital input class D amp (like the Technics and Lyngdorf)......this kind of amp changes the PCM signal directly to PWM (class d type of output stage). This type of amp eliminates your normal DAC and preamp......it is a DAC....it is a power DAC.....you cannot directly compare the two. One is driven by a DAC and has analog stages....the digital amp is driven by a digital source and has NO Normal ANALOG stages of gain......way more simple.......less is more.

No problem convincing me of this revolution with digital active crossovers, pure path digital amplifiers, switching power supplies, etc. , all of which actually happened a while ago. It all works for me. I prefer them by a long shot. But not everybody shares my preferences. They want to hear something a little different than I do. I hear problems with what they like. They hear problems with what I like. So the revolution comes and goes and they stick with their passive crossovers, tube amplifiers, etc. Whatever works for their ears is what they are going to and should continue to use. 

Not ready to give up my Hegel H30's anytime soon but I did find this review of the technology being discussed to be quite interesting.

@anzaanimalclinic    I'm a Class A only guy and not the dodgy Class A/B pretending it's Class A with so-called 'anticipator circuits'.

I can agree with @jerryg123; there's enough of us to ensure a ready supply of new Class A amps and a large stock of wonderful vintage ones.

@anzaanimalclinic Do not worry they are a long way from taking class A.

Now I am worried.

Beta was better than VHS, now it's gone.

HD video was better than Blu-Ray, now it's gone.

Now they are after Class A.

OK, of course there are transistors in the processor that does the PCM to PWM conversion along with the buffers afterwards and the GaN fets......but before that there are NO ANALOG stages with tubes or transistors......as in your DAC, Preamp and amp (all no longer needed)

you have to be kidding me, no transistors, not even in the digital front end or DAC as you call it, how can this be?

Finally a good sounding amp after 100 years!

Not sure how an amp can be characterized as excellent and then another in comparision - "Clearer, better imaging, warmer, less harsh, easier to listen to for extended periods, I can go on and on. It would seem the former is less than excellent, maybe good

I’m loving the sound from my Hifi Rose RA180 and NAD M33, both are excellent and rewarding to listen to.  Class D has come a long way.  But when I truly want bliss, I always come back to my Classe mono blocks.  Clearer, better imaging, warmer, less harsh, easier to listen to for extended periods, I can go on and on.  Class A up to 35 watts.

I'm very impressed with the quality of music I'm hearing with my Mini GaN 5 Power Amplifier.

And....... one more thread on Audiogon decends into a gradeschool level brawl.  I had such hopes for this site when I joined last year.  

@jerryg123   the likes of you will certainly be welcome in an intolerant forum.  Dream on about imaginary improvements to your system.  Some of us remain grounded in some kind of science.

@clearthinker not going anywhere, just the likes of you would not be tolerated.

So long Bubba. 

@jerryg123    Well off you go and leave us alone.

@arafiq you are right. Funny is none of this crap happens at WBF. 

@jerryg123 I feel you're wasting your time with the naysayers. It's highly unlikely they will change their minds. Let it be. There are a lot of us who like to explore new things in this wonderful hobby. Let's enjoy!

Snif.

@kuribo So no blind tests? Your logic is flawed because they are not published here? Only time you chirp in @kuribo is when there is a thread by @...

Can’t wait for my GaN1 + Node combo to arrive!

To funny the illogical claims.

On this day in 1903 two brothers were told it was illogical for a man to fly. 

@kuribo said.

@clearthinker  Google is your friend. Let people believe what they believe.

Sorry if this is over your head.

Thanks, ricevs..... I owe you some. ;)

Elons' learning the hard way....

This is not a "normal Class D amp".  It changes PCM to PWM in software and then drives a GaN based class D output stage.  It is basically a DAC....a power DAC. 

Isn't this what Technics did a couple of years ago? It's a proven design that works very well and sounds fantastic. So many ways to implement it. 

All the best,
Nonoise

Some people come here to share their joy, others come here to make people and things wrong. The anti tweak objectivists (flat earthers) are just best left alone. They will never stop saying the same thing over and over. They want to fight and argue.....you can never "win" with these people as they will always want the last word.......If you ignore them.....they will just go away. They add nothing to the discussion as they have NEVER heard the things they complain about. Sad, but true.

What is sad that some people have no idea how magnificient they are.....and when you realize how amazing and deserving and beautiful you are.....you also realize that everyone is just the same.......we are all amazing......At that point you stop pointing your finger at people because you know it is all projection.......when you point a finger at someone.....three are pointing back at yourself.......YOU ONLY SEE YOURSELF IN OTHERS. More and more I see beauty and worthiness in everyone....including the anti tweakers.......heck someone has to take that stance......a noisy few waving their flag with all their passion.....how cute. Kisses and hugs for everyone......forever.

Keeping this polite....bye bye @jerryg123   Happy hunting.

@clearthinker 

What is tiresome is hearing so many eulogising over the magical effect of some passive component or piece of snake oil on the basis of a totally unscientific test with accordingly meaningless results.  What is a lot worse is people coming here to sell this stuff to the faithful.

 

That about covers it. Willful ignorance is never pretty but sometimes people get what they deserve.

@jerryg123 

So no blind tests?  Your logic is flawed because they are not published here?

Sorry if this is over your head.

@jerryg123 :   And you know this how? 

Because no-one here ever reports blind testing that's how. 

Thank you @arro222 and @kuribo for your support here.

Yes @kuribo, clear thinking is often pure logic and sometimes just common sense, a commodity lacking in today's world.

@jerryg123 
 

And you know this how? 
 

Pure logic, which from this comment shows you are sadly lacking in a fundamental understanding of such.

@audioguy85 So freakin true. 

That's the problem with this hobby. People are always trusting someone else's ears. Some stuff I've heard that was supposed to be "exalted" made me wonder if the previous people who had heard, had ears.

Is this supposed to be an ad?

Stay away.

So basically this is a big sales pitch…

Glad to see some here aren’t fooled by more blatant, self serving advertisements. You would think by now the moderators would have put an end to this commercialization in a non-commercial forum. Sad. I would encourage people to report his self serving commercial appeals to the mods on a regular basis to flush this forum of people profiteering.

asvjerry, so if you fill the page with post after post of nonesense it will make the thread irrelevant?

Some people come here for reasons other than to discuss audio or music. I guess he’s one of them. I don’t understand it - it accomplishes nothing and just makes more work for the moderators.

@jerryg123    No I haven't.  I know snake oil when I see it.

More importantly, nor has anyone else auditioned any of this unless they have done it blind.

What would be good is snake oil salesmen setting up blind auditions of their oil, taking the auditions themselves and inviting us in as well.

The fact they don't do it evidences that they know this won't sell the product and that, in any case, there are enough believers around to keep them in business.

Ho hum.

Again @clearthinker have you auditioned any of these devices in your system? 

@fatdaddy2

I'm usually more on other forums because this forum seems to bring out aggressiveness or criticism despite the fact that this hobby is a very subjective one.

I am trying a Class D amp for the first time based upon some opinions of posters in another forum that I trust. Instead of sneering at it, I found that you can actually buy equipment on a trial basis in many places so there is little risk. 

I'm liking what I'm hearing so far but there are caveats to my enthusiasm such as I am listening to speakers in a different place and set up. As we all know, if you really want to test something out, you want to control all of the variables. I can't right now because I'm having some work done and my top speakers are being protected from construction dust. However, I'm hearing detail from the speakers I'm using that I hadn't heard in their previous system. Whether that is room related or amp related is something I will try to figure out.

Anyhow, I just want to point out that there is no sense in pooh-poohing (or doo-dooing) something new without trying it. It may not work for everyone's ears or there may be no synergy with everyone's system but a poster who is excited about something new shouldn't hear boo birds just because some posters have engrained biases. Pointing out factual problems is fine. Booing an opinion, to me, crosses a line.

I'm very impressed with the quality of music I'm hearing with my Mini GaN 5 Power Amplifier.

Music Purifiers, Ground Enhancers, Bybee Clarifiers, oh dear, what nonsense.

No one ever got something for nothing.

Not only emperors are taken in by new clothes.

Stay away.

asvjerry, so if you fill the page with post after post of nonesense it will make the thread irrelevant? Or do you have some other motivation for these posts?

I just watched a woman describing her Near Death Experience......she said she went into the light and through a tunnel and God grabbed her hand......she was overwhelmed with love like she had never experienced. God told her she had to go back and she pleaded with God.....saying that she is so loving and takes care of everyone (she seriously wanted to stay there). God said.....well, did you love them the way I am loving you? And she replies.....well, I am just human........and God looks at her and says "You can do better".......and two seconds later she was back in her body. This is what the soul is doing here.....learning to "do better"......

Everyone.....What is your better? Please show us. You are all loved, you are all worthy. Please give the best of your love. We all want it.

@asvjerry g’day mate, eeeewwwww!
