GaN amps: Peachtree or LSA Voyager?

Ah!  I have it  now. Jeff Rowland is what you need.

@twoleftears Ha! I have Rowlands. Well, sold one 535, still have the other. Had a Model 2 for years. And a Synergy pre. Jeff has pulled all his D's off the market. I don't know if he is rethinking his involvement with class D or getting ready to do the latest D tech. 

Unless you like load dependent frequency response like the old Tripath class d amps from 20 years ago, I would avoid the Peachtree or LSA Voyager modules like the plague. Old class d designs with the latest flavor of the month, GaN. Too bad they use too low of a switching frequency to exploit the real advantages of the GaN devices.

Orchard on the other hand has a state of the art design and while they still don't use a switching frequency high enough to really get the benefits from the GaN devices at least they use a proper circuit and don't have a load dependent frequency response.

There is also Purifi which is the current state of the art. They don't use the GaN devices because, well, they see no need- they have a very clever design which produces an amp with stellar performance, both measured, and, if all the reviews and customer opinions are to be believed, has great subject performance as well.

Look into Purifi and Orchard. There was a review of Orchard's amp in the latest AudioExpress I believe.

The Voyager/Peachtree modules designed by EAS are the latest thing from them.  The reason they do not measure as well as Purifi and Orchard is that they chose to use very little feedback (20 db....decided by listening tests....something Kuibo does not understand).  Purifi and Orchard use a ton of feedback. 

As far as switching frequency.....this is arguable....at best.  

Please, do not listen to me or anyone else.....listen to the amps and decide for yourself which one is for you.  All of them have rave reviews.....If you want to decide beforehand based on measurements....then fine......but don't think your super fine measureing amp is the best sonically.  I modded the Purifi based VTV amp so check out 10audio.com and read his reivews of the NAD using this same module versus my modded VTV......he gave the NAD a 6 and my amp a 9.5 bordering on 10 (10 point scale)......this is for sound, of course.....he did not measure them.  Every single thing you do to an amp changes the sound.  I can improve the Orchard, as well.....very easily....and yet, it will not measure one iota different.  This game is infinite......just like our infinite nature.....enjoy the infinity.....and beyond!

Here are links the the reviews that were mentioned above:
