What are the best GaN Amplifiers available today?

I have not heard the Peachtree but from what I have read it is just OK at best.

GaN got a lot of hype early on here. It is a technical advancement but no one thing alone assures a superior product. It’s all in how well designed and implemented a product is overall. It usually takes some time for engineers to fully realize any new technology fully. So the rule with new tech is always the longer you wait the lower the risk. New technology gets done better and often more cost effectively over time.

I’ve determined that the problem with forum anecdotes with regard to amps is that many are lacking a good point of reference. Someone will chime in saying that an amp like the Starkrimson powered their Magnepans or ESLs well, yet this person probably wouldn’t say that had they compared the amp to a big Krell on the same day. That or they will be comparing these amps to a mid-fi offering from a competitor.

Suffice to say I suspect GaN FETs with regard to amps are mostly another flash in the pan technology that hasn’t really moved the needle. There may be exceptions of course, but I am highly doubtful at present.

@helomech Reference is a big deal IMO/IME. I use LPs and CDs that I recorded and mastered myself. It helps having been at the recording session. 

@mapman GANFETs have been around since 2009. They became much more commonplace about 2016; at that point most of the major US players had their own version of the devices and they became a lot less expensive. 

@helomech  Hey man, Stick with your class A/ AB Amps. But Class D is no flash in the pan. They are becoming an ever increasing market year after year and are starting to take a BITE out of your A/ AB sales. Aavik..Peachtree...Atma-Sphere...Jeff Roland....Orchard...AGD.....good stuff and MORE MUSICAL to many than A/ AB.  I do enjoy a Big Tubed Preamp with a ClassD Amp however.

I've got a Technics SU-R1000 which I think is pretty brilliant and is the first "digital" amp that I have really liked.  I also had its baby brother in to play with for a couple of weeks and thought that was excellent as well.  I had a NAD M33 for about three months and couldn't get rid of that fast enough.  

It's tough to compare the Technics to some of the others because of all the additional features that it brings to the table, so not really apples to apples.  There is a gentleman in the area who has the AGD monoblocks and I would love to spend a day with him comparing the Technics and the AGD.  I may see if my dealer is willing to loan me his AGDs for a long weekend as well.

I'd also be interested in comparing the Peachtree with the Technics G700M2 as they seem in the same price ballpark.  Sorry I can't offer more, I just have not heard any of these in the same room with the same equipment.
