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?

@mahgister  12 volt is  best to start out with. 12v Inverters are less expensive. I have 24v system but use 2 batteries for emergency back up outlet charged by solar panels.  I haven’t set it up for audio.  

Here’s a more economical battery set:

I am not sure the inverter recommended by ricevs has a low noise floor and  is good for an audio system...

One reviewer say this :

Reviewed in the United States on May 14, 2023

Size: 1500WVerified Purchase
First the good. Outputs at rated capacity with no problems. Fans move a lot of air to keep inverter cool. I had no problem mounting it sideways to read display after seeing how much air the cooling fans move. Display is readable at a distance and gives valuable information.

The bad. I bought this because it was FCC approved to be within standards of emission of RFI. For Ham Radio Operators, this is a very NOISY inverter that will give you over S 9 noise floor.

I recommend that particular 2000 watt Giandel inverter because it is FCC approved so may have lower noise.
