LSA Voyager GAN Amplifier

I got the Peachtree GaN 400 the other day.  So far it sounds great.  It is a bit hard to tell without taking apart the case, but it appears to have identical, or nearly identical, internals to the LSA Voyager GAN 350.  Is a third party supplying complete modules to these new GaN amps? The Class D Audio Mini GAN 5 is a completely different build but it is still burning in for a few hours before I listen to it.

I have formed some preliminary thoughts on the Peachtree GaN 400 vs. the Class D Mini GAN 5. I have both amps hooked up to the RCA outputs of my Schiit Freya Preamp using its solid state stage and either the SMSL SU-9 or Denefrips Ares II DAC running Roon/Qobuz. The output of the amps is hooked up to an A/B switch with is connected to my Tekton Moabs. Cables are identical for each amp. The GaN 400 has about 40 hours of burn in and the GAN 5 has about 11 hours of burn in. Before I got the GAN 5 I was comparing the GaN 400 to my DIY First Watt M2x which has become my favorite amp compared to other First Watt amps as well as the PS Audio M700’s and Willsenton R8.

The Peachtree GaN 400 is a great amp. It has a level of detail, spaciousness, clarity, and tonal purity that I haven’t heard before. The soundstage isn’t wider than the M2x but it is airy and more spacious and quite a bit more holographic. The music sounds like it has been unpacked and a veil lifted. It also has great dynamics. Bass is tight and fast and the highs are detailed and crisp without being edgy or fatiguing. Male and female vocals are very clear and natural. But, the amp doesn’t have that liquid, wet tubey sound. I have never owned a 300B amp but my guess is the sound is more like that rather than the thicker sound I get from my Willsenton R8. The midrange has that clear tonal purity of the First Watt F6 or my Dennis Had Universal SET running 6L6 tubes but with much more satisfying bass and even more separation and richness overall. The GaN 400 gives the music a level of vibrance and immediacy that is quite remarkable and I haven’t heard any glare and I don’t find the amp fatiguing. But if you want that very wet, smooth, warm tube/vinyl sound it might not be the amp for you. I want to listen more and do more comparisons but I’m pretty sure this will become my standard amp.

The GAN 5 has a lot of the same qualities of the GaN 400 but with a touch more warmness and smoothness. Bass is different also, a bit less tight and a tad boomier. The biggest difference is in that sense of spaciousness, clarity, separation and tonal purity. The GAN 5 simply isn’t as good or dramatic in those respects compared to the GaN 400. The GaN 400 sort of demands your attention because each element of the music is distinctly separated while the GAN 5 is more 2D and smoothly mushed together. I haven’t gone to the trouble of replacing the GaN 400 with my M2x so I can’t make an informed comparison there but my guess is that the GAN 5 sounds quite similar to the M2x which is a pretty high compliment in my book.

The GaN 400 gives me something I’ve never heard in my system and I like it very much. I think I am going to be more than happy to trade off some midrange richness/liquidity for the extraordinary level of detail, spaciousness, and separation that I hear with the GaN 400. The GAN 5 is a very good amp, especially at $750, but it doesn’t give me that wow factor the GaN 400 does. Given the price I don’t think I would have any trouble recommending the Mini GAN 5 but I think the Peachtree GaN 400 is the one I am going to keep.

I am also going to post this as a new thread so it will be easier for people interested in these two amps to find.

ricevs - I'm not willing to take the cover off the Peachtree until I am certain I am keeping it although my initial impressions are that it outperforms all of my other amps by a significant margin.

So what sort of mods do you do and how do I find out about them.  I saw a post by you mentioning a website but no address.

The chassis of the GAN 5 is steel.  The GaN 400 is non-magnetic.  Since the GAN 5 is probably going to be returned I'm not going to open it up so see if removing the top makes any sonic difference.

The GaN 400 is organized quite differently internally compared to the picture of the Voyager but there is a sort of screen on the top of the GaN 400 that lets you peer inside to a limited extent and the layout of the components seems identical to the Voyager.  Now I could be wrong about them having identical modules because the view is so restricted and I can't see the totality of the board.
