@wise Santa B why do you expect delivery next week? I am waiting too.......
Thanks for this thread folks I NJoy it! U R All WAAAY above my pay grade
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!

@donnylovely "...complaining about some "issue" that no one cares about" Seriously? This is certainly something to care about, if you have any clue about amps. Until these new wonders can run my Acoustats, or any difficult load, they're not worth a dime. Heaven forbid manufacturers post their 2-ohm ratings! I dare anyone owning this amp to send it to ASR. Yes, I know they don't give a damn about sound quality. But they do give a damn about the flip side of the audio coin: measurements. |
@kuribo the guy in denial, which would be you. You haven't given any facts. |
@art_boston I stand corrected, only 2 people care about. I only care about sound quality. I'll never send my personal stuff to those jokers at ASR. They can buy their own gan 1 and be smug about their measurements. |
He is clueless, don’t waste your time. The FACT is open loop (zero feedback) amps are load dependent - the output filter interacts with the load, that is one reason why modern designs use feedback after the output filter. Simple physics which can't be ignored, as much as one tries.
That’s the gist of the problem, isn’t it, with amps that have load dependency? For modern designs which avoid that issue it isn’t a thing. Try something with a flat impedance curve that is basically a resistive load. Good luck. |
