The revolution has begun!


Digital amps along with digital xovers are the future.....and you can have it NOW. I am not going to say that a $1400 Peachtree GaN1 amp will sound better than a $120K MSB Select, $145K Boulder Preamp and Bouder $250K mono blocks with $20K worth of cables in between (over half a million plus power cords and amp stands)......but it did beat the Holo May KTE with the Holo Serene Pre and Kinki B7 mono blocks with $1000 worth of interconnects ($13k). So what will it take to beat this $200 digital board from Elegant Audio Solutions powered from a $100 switching power supply? With a digital amp you do not need a DAC or a preamp or regular amp with feedback, tubes, or transistors. With digital amps you can bi or triamp your speaker drivers directly without the distortion of passive components. In fact, I would bet that if you bought two GaN 1 amps, bought the $600 digital xover from minisdp (with great linear supply and great coax cables) and biamped some drivers directly that it would sound better than most $50K systems. You could get 2 12 inch woofs and mount them on an open baffle and put a beryllium tweenter on top and set the xover to 1K or less (48db per octave). You hardwire your speaker cable to the woofers voice coil wires and use Music Purifiers and Ground Enhancers on each driver.....Bybee Clarifiers on the back of the woofer magnets.......speaker wires hardwired via plastic clamps into the amps (no binding posts or spades allowed here!). Of course, you can triamp.....and manufacturers will soon have powered digital speaker so all you will need is a source.

There will be other manufacturers designing and building digital amps that will (no doubt) be better than the EAS boards.....but they will come at a price. These, yet to be made digital amps will blow the industry wide open....as no more big heavy expensive boxes will ever need to be purchased......but what EAS has not is fantastic. When I do some mods to the Peachtree amp next month it should get a step or two better. Have fun!

I have started a webpage about all this and more and will be updating it continuously.

Not in the sense you mean, only make and do a few tweaks/mods. I am excited about these digital amps and the possibilities for incredible sound.....have been around and in the business since the mid 70s.

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.  The advantage is.....no preamp, no normal DAC, no normal amp and no analog cables in between.  If the "less is more" thang works (and usually it does)...then this is the shortest signal path in existence.....especially when using a digital xover and then you don't need veiled sounding coils, caps, and resistors inside your speaker......this will blow your mind......but, most of you do not understand this or believe otherwise.....that is fine.  For those who really look into this.....they know.....they know this is the revolution that will change forever how amps and speakers are made.....will take at least 5 years to fully be in place as ALL the dealers hate this idea (cannot sell their big, heavy and expensive multi box systems), and most of the manufacturers are already invested in the old paradigm and want to sell you their heavy expensive boxes.  The Peachtree GaN 1 weighs 12 lbs. (200 watts a channel).

Don’t think Bruno has ever mentioned digital based Class D. He uses normal class D with TONS of feedback. The digital amps have NO feedback. Regular class D needs a DAC in front of it......the digital amps do not. Very different. What is interesting is that Purifi has most of the founders of TACT (Tocatta Tech) that made the first digital amp back in the 90s. It would be very easy for them to design a digital amp......but I guess they are hung up on measurements. A digital amp (because it has no feedback) will not measure anything like a Purifi or Hypex or Orchard. We are talking .05 distortion versus .0002. Do you listen to numbers or do you listen to music? So far, everyone (very few ) who has heard the Peachtree has preferred it to other amps (including the latest high power Purifi).

There is no perfect sound forever.  Digital amps will evolve just like everything.  We have only just begun.....but please keep firing away.....he he.

No, a digital amp does not have a DAC in it.....it is the DAC. This is not a normal Class D amp and should not be compared to it. A normal class D amp needs a DAC in front of it and has analog stages in it with feedback. This has no feedback, no opamps, no transistors, no tubes, no normal DAC...

Of course, Tact did this first.....please read my website. Does not mean that today we cannot do it better....even much better.

So it only has coax input. There are tons of streamers and ways to add all the inputs you need. The $2400 Lumin U2 Mini has LEEDH lossless digital volume control and will play all kinds of sources and even takes DSD512.

What really matters is how is sounds.....more comparisons coming soon.......and the biggest thang is that you can use pure digital xovers.....so everyone will be getting new speakers with no xovers in them or making their own and having sound that is better than they have ever heard. It is commonly known that active speakers are better than passive......and that is with the crappy electronics that is in the current active speakers (crossovers using normal DACs and normal amps). When you hear the zero sound of a digital xover plus digital amp and then direct to your drivers so will be sobbing in happiness.

I don’t trust professional reviews.....they are mostly ads. The person that has the Holo set up is much more trustworthy. He is not getting paid.

As I stated in my webpage we have just begun. Someone could make a version with this EAS board (or the 400 watt stereo board that has multiple inputs including usb) right now. This is just the very first product usng this board and Peachtree wanted to get it out fast. But, as I said, if you bought two of these GaN1 amps and biamped using the minidsp pure digital crossover and ran the speaker wires directly to the voice coil wires on your speakers.....oh my GOD. You can do this right NOW.

This is an excited enthusiast sharing with the world the great new audio frontier.  Cheaper and better.....something to be excited about.  Have you ever been super excited about something and you knew it would serve everyone?.......Wouldn't you share the information with all your passion?  I feel good.....as James Brown sang.

If you buy some of the new digital amps and you love them and it makes you happier then send me some money.....he he.   I sell happiness.....of course, it is free.....

What is even more exciting than audio......is your self......your beautiful self......you are blessed, you are loved and you are infinite joy and happiness.....and you have always been so.......60 trillion cells in your body dancing in divine harmony.....every frickin second is the most beautiful second that has ever been........yup!  way more far out than audio........you are amazing, magnificent and worthy....enjoy the ride!

Love yourself, love everyone.....love everything....love every second......why not?  You can and its free.

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.

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.

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)

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.

bigtwin,  You don't understand.  How many times do I have to state this:  This is not a normal Class D amp like the Orchard in the review you posted.  The reviewer has never heard this "digital" amp so he has no reference to this amp nor do you.

Peachtree 400.....AGD.....these are all normal class D that require a Dac in front of it and analog stages in the class D amp.......THIS IS DIFFERENT.  This thread is not about normal class D........but this a DIGITAL AMP!!!!!

Yes, I know about the Exogal......very esoteric, and you have to use it with its own pre/DAC and the cost is high and the power is not great......and you cannot do room correction, bi amp, eq and do whatever.  You have to realize that the inexpensive EAS boards are 4 channel boards.....for instance the 400 watt stereo boards are 4 100 watt single ended channels.  So, if you wanted to use one board for mono tri-amping....then no problem.  Two channels get bridged for 400 watts for your woofs and 100 watts for your mid and highs.....built in to the board is a fully progammable processor (software comes from the manufacturer to set it up any way you want.....xover, eq....whatever....all on the same board).  You could mount one board inside a 3 way speaker and program it to do everything and just drive the board digitally......this is way cool.  Of course there are already boards made like that that people use but they are using conventional DAC chips and op amps on the output of their digtital processor and then using conventional class D or A/B afterwords.  This will be simpler and sonically purer and can be done very fast.

Imagine the fully digital integrated amp with at least 4 inputs, LEEDH lossless volume control, full dsp and 8 channels of amplifier output.  You could mount some drivers on an open baffle and just run wires to the drivers and do all the xover points and eq and time aligning yourself in an hour......sit back and have the best sound you have even heard......this is coming.  ONE FRICKIN box and drivers on a board.......you will play with different drivers instead of saving up for the next 100lb class A amp that costs $100K (that won't give you anything you don't already have)......this is the future......of course, powered speakers will be cool....but who wants to listen to the same drivers all the time.......got to have something to do.  We will all be on forums talking about the latest drivers we have listened to.....amps and preamps and DACs will be dead......for the old fogys.

Infomercial? I do not sell amps using the EAS modules......You cannot tell the difference between a super enthusiastic person who thinks EVERYONE should know the good news and a salesman?  What if I was preaching religion?.....actually, I preach love.....who is getting paid?  We all get paid in happiness by sharing our knowledge and love with people so they can flourish.  Love is its own reward.  Go on......get excited about something!  WE ARE ALIVE......Live this moment.....it is the ONLY moment you ever have.....there is only the NOW.......you choose to enjoy the now or to resist it.  I choose to enjoy.

There are studies that PROVE that giving makes you happier.......Be of service......lift each other up.....lend a hand....spread the good word on things that are truly worthy.....and doable.

A serious advantage of a digital amp system is that you can add....or use alone the $500 Minidsp flex.....for tweaking your system or bi-amping. If you have a CD player and that is your only source then you can buy the Flex and use it as your volume control (it has coax digital in and out)......and also use it to completely eliminate room nodes and equalize your speaker.......a big deal....way cleaner sound. Then, if you want to bi-amp your speakers, you can.....either keeping the passive xover in your two way.....or making your own two way speaker......So, that is CD transport to $500 flex to $1500 digital amp and then to your speakers (now totally equalized) or add another $1500 amp and biamp with eq. If you need to stream and use other sources, then you can use the IFI Zenstream or other streamer ahead of the Minidsp and still either equalize or biamp.

All rooms have bass nodes....when eliminated....you have much cleaner sound and better imaging.......So, great digital amp sound plus MORE.....much more.

How about 2 12 inch woofers on an open baffle and above it an AMT or Beryllium tweeter.......biamped.......or a slim box with 2 6.5 inch Purfii woofs and a super tweeter on top of the box.....for dipole highs above 1K......so easy.....so pure sounding to biamp using digital amps and the flex. Lot’s of incredible possibilities......imagination is key.

A "transport" is just the spinner in a CD player.  Almost every CD player has a coax digital out so can be used as just a "Transport".  Your Audiolab has no DAC in it so you call it a transport rather than a CD player.  Any player including universal players like an Oppo can be used via its coax out to the flex and into a digital amp.  However, you cannot play an SACD into the flex.....nor is SACD info allowed out of a normal coax out.  The amp and the Flex are PCM only devices.  You could make an integrated amp with digital amp modules where you change DSD info to PCM before it goes into the main pcm to pwm conversion.....Technics does this.  You can burn your SACDs to a computer and use software in a computer to change it to high speed PCM and then output that to a streamer like the IFI Zenstream to play through digital amps.

You get a Flex and a single stereo digital amp and you have a blast....you add a second amp and get rid of the crossover in your speaker and you are in heaven.  No more bass nodes.....full equalization......no more binding posts....no more passive xovers.....just pure sound.....dynamic as hell.  Fun times await folks......the future is now!

VTV just released a digital amp that uses a more powerful version of the EAS board.........The VTV D300 is now being sold:

The reason it says Purifi on the faceplate is that he does not have any faceplates with D300 on them....He will allow you to change the faceplate for free when he gets the right ones in. I don’t think it even needs to say anything on the front except VTV.

The reason he rates the amp at 300 watts into 8 ohms when the module is rated at 400 watts is that the power supply dips in voltage when doing full power tests with both channels at the same time. If you did peaks on one channel at a time you would indeed get 400 watts of unclipped power. Most music has peaks that require the higher power.....hardly any music requires 400 watts continuous on both channels......and if you played it that loud....you are not smart......hearing loss, indeed.

The WBT-0703Cu jack option is a nice upgrade. Of course, I will offer mods on it. The digital amp game keeps getting more interesting. I cannot wait to bi-amp my speakers with these things.
