GaN amps: Peachtree or LSA Voyager?

Peachtree 400 and LSA Voyager GaN amps: Does anyone have direct experience with both of these amps? Can you comment on any differences that might exist in sound? I know the internals are supposed to be the same but even if that is true implementation can make a difference. Both are highly regarded by those who own them.

Might also be helpful if you listed the rest of your system (Pre and speakers).

My current system is: Bricasti M3 DAC; Rogue RP-7 (NOS) pre; Bel Canto Ref600M amps; Fyne F1-8 speakers.

Thanks in advance!


@pehare A dealer loaned me a pair of the Atma-Sphere GaN monos. They are indeed very nice. Interesting that they have a big toroidal transformer, the only D I have come across that does. I could eventually end ups with a pair. Just wish they had more power. At the time I was still using my KEF Reference 1s which benefit from lots of juice.


It will be interesting to read your comparison of the Voyager and the Atmasphere Class d monoblocks.  Based on the specs of your appears that the Atmasphere could easily drive them to over 104db at a listening position 10' back so I'm not sure more power would really be of much value, especially since the speakers are rated at 90 watts max continuous power handling.



When I had the Alma-Sphere monos I had not yet acquired the Fynes. The KEF Reference 1s that I was using at the time need a lot more grunt in an amp than the Fynes.

I no longer have the Atma-Spheres here to compare to the LSA. Listening at the moment to the AVA 225 monos on the Fynes (an excellent combination by the way). Going to insert the LSA in a few minutes.

The AVA's will also be an interesting comparison as they have had a lot of good press lately as well.

First impressions, and a qualifier: My comments relate entirely to my system and my sensibilities. Both the AVA 225M and the LSA Voyager GaN 350 are superb amps in my opinion. These are my FIRST impressions:

It is closer than I expected it to be. The LSA seems to have a blacker background, better decay, better rendering of textures, better detail. I think the AVA has slightly better global dynamics but has more of a tendency to break up on dynamic peaks (maybe from switching into AB?). Or maybe it seems that way because the LSA doesn't break up. The LSA has better micro dynamics. Imaging is a little better on the LSA. Both amps are what I would call slightly warm. 

Both the AVA 225M and the LSA Voyager GaN 350 are superb amps, and each is a steal at the retail price. As things stand now I am going with the LSA. I hear nothing negative and lots of positive. But again these are first impressions that might change. If they do I will update this thread.
