Peachtree GaN 1 Beta

Before I start my post here is my current system for reference:

Auarlic Aries G1 --> Denafrips Terminator or SW1X DAC --> Audio GD HE1 XLR preamp or Sachs preamp --> various tube amps --> Cube Nenuphar Mini's w/ a pair of REL S510 subs. Cables and power conditioning commensurate with the rest of the system.

As warmer months approach I have been looking for a cool running amp to replace my Line Magnetic LM-518 and other tube amps for a few months as they run pretty hot.

I've been interested in the GaN FET amps and just purchased a used LSA Voyager 350 Gan FET amp which I should receive in a few days. I've tried class D amps before and while they checked a lot of boxes I just didn't feel drawn in. However, I like to explore so I figured I'd try the GanFET and since the amp has zero feedback and my speakers seem to prefer amps with little or no feedback I figured it be worth checking out.

Today, Peachtree Audio sent out an email inviting users to a beta of their new Gan 1 amp. Here are some excerpts from their email:

 

What is the GaN 1?

In basic terms it is a 200 Watts-Per-Channel (WPC) Power Amplifier designed to be the sole interface between your digital audio device with a variable output, like a Bluesound NODE, and your speakers. The GaN 1 is a simple, pure and cost-effective audio solution: connect the GaN 1 to a streamer and a pair of speakers and you have an amazing Hi-Fi system. That's it...no DAC, no preamp and no input switching. The signal path from the music to your speakers is remarkably short and free of artifacts. Want to hear the intricate details in your music that have always been there, but you couldn't quite make them all out before? Then the GaN 1 is for you!

What makes the GaN 1 so special?

First and foremost is the GaN-FET amplifier module. It has several inherent advantages in a power amplifier that even the best MOS-FET designs simply cannot achieve. A GaN-FET power stage provides a precise high-power reproduction of the Class-D PWM signal with extremely high linearity. This linearity eliminates the need for ANY feedback, ultimately allowing for the best possible audio quality providing clean, clear middle and high frequencies and a tight, solid reproduction of low frequencies. GaN-FETs track the complex audio waveforms MUCH more accurately than MOS-FETs, resulting in significantly more transparent and natural sound. The difference is something even a casual listener can hear and appreciate. The GaN 1 is also designed so that it does NOT require a digital-to-analog-converter (DAC). The digital audio signal at the input directs the amplifier outputs to drive the speakers. Although DACs have continued to improve over the years, there is no DAC better than NO DAC! This concept is not new as similar devices known as "Power DACs" made quite a splash in our industry years ago. But this time around, by executing the concept with GaN-FETs, the bar is raised to an entirely new level.

Key Features at a Glance:
▪ 200 WPC state-of-the-art GaN-FET module
▪ ZERO feedback design
▪ Regulated 450-Watt power supply
▪ Coaxial S/PDIF input with native support up to 24-bit / 192kHz
▪ DAC-less design
▪ Power on/off trigger port
▪ All aluminum chassis
▪ No cooling fans

 

This sounded really interesting to me and since I have a good streamer I signed up for the amp beta only. One aspect that intrigues me is to create an extremely minimal signal path. My speakers are single driver, crossover-less design. Employing the GaN 1 will mean the system will be Auralic Aries --> GaN 1 --> Cube Nenuphar Mini's. Will that lead to a more engaging sound vs the full system? Will the Voyager GaN 350 outperform a tube amp in the full system? Who knows, should be fun to find out....

Now, I have no idea how either of these GaN FET amps will work with my speakers. The Cube Nenuphars seem to prefer amps with low damping and no negative feedback, which is more common with SET tube amps and Class A solid state amps. I'm not sure of the damping factor of the GaN FET amps, but both are Zero feedback designs, and both have way more wattage than I need. For reference, I have a 1.5 wpc 45 tube amp that sounds amazing with the Cubes, so high wattage is not required. I am interested though in what these amps will sound like compared to my tube amps, and I am particularly interested in what the streamer direct to amp Peachtree will sound like.

I am also looking to acquire a First Watt SIT-3, which is a great match with the Cubes, but now that they are no longer produced prices have gone above my current comfort level. If I can get one I will throw it into the experiment.

The Peachtree won't be shipped until sometime in June, or possibly later. In the meantime I will get the LSA Voyager in the next few days. I might even be able to get it hooked up this weekend so stay tuned, should be an interesting experiment...

Always the go to fallacy: "people who criticize don’t listen"...just another deflection.

Who are you to decree that just because people trust science, logic, and reason rather than your self serving, self interested fairy tales, they don’t listen? Maybe many have and the issue is in fact that there is nothing to hear amongst the unsubstantiated, unproven-or should I say disproven?- claims you make (and make money of off)? Who are you tell everyone that your hack jobs will universally improve the sound of an amp? Even if your "tweaks" actually improved the performance of an amp, there are sure to be people who don’t think they improve the sound- tastes differ. Talk about fantasy...

It’s not slander to call out the truth. First, prove your "tweaks" actually do something other than degrade the performance of an amp, then prove that whatever you’ve done is universally accepted as an improvement. You can’t prove or verify your claims, yet you are a non-stop ad machine always sneaking in your services here on this hobbyist board, always spewing the same unsubstantiated claims. Audio is full of charlatans always ready to fleece the unknowledgeable and insecure. You might fool 90% of those on this forum but you won’t fool everyone.

Of course your disagree with Ralph- what could someone who actually designs and sells equipment possible know, compared to someone who makes a living off of other people's work, jumping on every new amp with fantastic claims of "improvement"? To actually think that some solder gun jockey could actually somehow know better than the designers of these products really is beyond the pale. Kind of like some 6th grade kid with a watch teaching Stephen Hawking about time...

This thread is dead. Mr Charming is up to his old tricks.

Call me crazy.

Crazy is thinking that someone who makes a living selling dreams will ever wake up to reality.

Its very simple.....those of us that trust ourself and listen on our own.....know the truth.....those that just speak of science as truth.....and don't listen......do not know the truth.....end of story.  Everything else is just blah blah blah.

Trust your ears....you will know what works and does not work.

Do not trust what I say....or anyone else says.....only trust your own experience.

This is true self love....trusting yourself....loving and enjoying your own experience.  No one knows better than you......when you allow yourself to trust.

We are amazing.

I am amazed at how much I have learned about audio and about life this last year......tons of new things.....digital amps, Music Purifiers, Inverter power, using plastic (no metal) for speaker clamps, Bybee Claifiers....etc.  always more to explore and learn.....just as the soul learns to love more and more.....so the mind learns to open more and more to the possibilities.

I would purchase anything that atmasphere sells without hesitation.

Insinuating that the design Ralph took years to create can be improved by applying a laundry list of mods sounds really off base.

And I think that anyone implying that the vast majority of audio engineers, scientists and other professionals in the field do not listen to their creations as much or more as anyone else is truly moronic and not worthy of being printed.  Yes, there always will be an outlier.
