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?

Ralph is in in the room. Cool. Met him at Axpona. Great guy with great stories. Thanks to jeffseight for introducing me to Ralph.

As an update. I'm still running Orchard Audio on my Center and Surrounds. I got a killer deal on a pair of Black Ice F100's that I couldn't pass up.

I've also listened to a pair of Atmas-Phere Amps that Ralph designed on a pair of PS Audio FR30's. They are a good match. 

I tried orchard starkrisen, if you never compare it you’ll like it it is very good but my Hegel h360 is much better 

@nickintroy Which one did you try, Rev 1.0 or Rev 2.0? Did you have one with an upgraded power supply? In what ways is the Hegel better?

Earlier in this thread I mentioned I was impressed with the Cambridge EDGE A. There has been more than one review where it compares that amp to a Hegel H590 which is $12K or so, and it seems the Cambridge outperforms the Hegel. If you’re saying an even lower tiered Hegel beats the Starkrimson, that’s eye-opening and makes me want to drop it from my consideration set. 

I found @nickintroy’s evaluation surprising as I have a number of customers that replaced their H390s with the Ultras.

The configuration that he used was a V2 with a single power supply and upgraded capacitance ($3050 MSRP)
