What are the best GaN Amplifiers available today?


There have been a number of threads discussing the wonder of GaN and some of the individual amplifiers that have caught peoples attention, including those from AGD, Atma-Sphere, Peachtree, LSA, etc. Has anyone done a shootout against two or more GaN amps? If so, which did you prefer, and why? And on what speakers?

Also, of the one you preferred, do you prefer it over every other amplifier you’ve ever heard? If not, what non-GaN amp do you enjoy more?

I own the Peachtree GaN 400......Absolutely love the way it takes a signal and makes it sound "live". I’m using an Audio- GD ...HE1-XLR SE as a Tubed pre with an Audio Mirror Toubadour IV- SE DAC and Borresen X-3 speakers.To me this is as good as it gets.I’ve been to many shows and rarely do I experience anything this Musical a "you are there" sound. I am "inside" the music. An experience I’ve never felt in 40 years of Audio.I also own the Aavik U-150 Pascal class D. Totally different sound. ...But the MC phono pre and built in DAC is world class. I personally don’t forsee ever going back to My KT-88 and 845 Tube amps....The Decware I’m keeping ’cause it’s fun with my High- Efficiency speakers ( Klipsch / Texkton/ JBL.....I'm a firm believer in " System Synergy"....and there's only one way to achieve that....Try lot's of different gear. I've been with Alberto and his gear is Awsome also. Best of luck to you.

Which AGD amps did you compare to the Atma - were they the Audion? Would you characterize them as rolled off on top, or just sweet?

@blisshifi If you look at the comments comparing the Atma-Sphere amps to the AGD, you'll see that they contradict each other- some say one is sweeter or darker and the other the other 'way around. FWIW the Atma-Sphere has bandwidth well past 30KHz, so of someone says it sounds 'darker' or the like, its not because of frequency response- its due to how the amps in comparison make distortion.

@atmasphere I noticed that, and FWIW, hearing your amps between AXPONA ’22 and FLAX ’23, I thought they were anything but rolled off. Maybe since you’re now on this thread, could I ask you to share how you voiced your GaN monos, especially in comparison to your OTLs? Did you attempt to preserve the same level of openness and bandwidth to your other amps (albeit making it easier to drive speakers with)? How would you compare the sonics of your GaN amps to your OTLs? As you know, I was very fond of the MA-1, and later on the S-30 that I had you fully upgrade.

@mbmi Do I understand you right that you prefer the Peachtree to the Aavik? Also you are comparing an integrated (the Aavik U-150) to a power amp with a separate preamp. Is there any way to bypass the preamp section of the Aavik and use your Audio_GD with it? Thanks.

@ricevs I am not familiar with your modifications, the same question as Tjag above, can you describe your modifications and how each one effects the sound of the amplifier? Which amp is your favourite for modding?
