What are the best GaN Amplifiers available today?

I recently tried the Orchard Audio Starkrimson Stereo 2.0 and I thought it was a fantastic amp.  It drove my Magnepan LRS+ very well.  I'm no expert at describing audio gear but the clarity, texture, mids and bass were well done.

GaN amps are not unlike other amps and each manufacturer has a slightly different interpretation and the resulting sound can be quite different.  I have a customer who just did an Atmasphere vs. AGD test.  Both amps are great.  He liked the AGD better because it sounded more like a stereotypical MOSFET design which is quite tubey sounding.  His system needed a more musical amp and he looking to move away from Leben.  If his system was more musical, the opposite result might have been the case and the drier Atmasphere amp could be a better fit.  

I personally have tested Peachtree vs AGD and again, the Peachtree is brighter and more sterile.  It doesn't make it bad, just different and needed to be paired with different speakers.  

There is never an objective "best" amp.  It is what is best for your taste in your system.  

Not sure of your budget but Aavik is one of the best names for SQ.

Pricey of course. 

Some rave about the NAD. Not heard it. 

Have heard Orchard, Peachtree, LSA, Atmasphere, Aavik, Bel Canto.

But all with different rooms/speakers etc. 

I proposed to do a shootout with the top names in class D

but the field is still growing so it would be a task.

I have had 3 GAN amps. Just re-bought the PeachTree GAN400 yesterday.

The best GAN amp I have had was the PeachTree GAN1 that was mentioned above, however, mine was modded by Ric Shultz at Tweak Audio. TheGAN1 went from an OK amp to almost the best system (not just amp). Something so good I sold $15K worth of gear. I sold the following

- Benchmark AHB2 monos

- Lumin X1 DAC/ steamer

- moved my Benchmark LA4 preamp to another system since it could not be used anymore with the GAN1

Maybe more gear, I cannot remember (too much work today).

The GAN1 was not better than the above gear but it was as good with the KEF LS50 Meta. The GAN1 was stronger on the bass and the AHB2 was a bit sharper sounding but the detail level was the same. STOCK GAN1 was nowhere sonically close to this.

The second best GAN1 I have owned is the Peachtree GAN400. The GAN1 is a PIA to use and it cannot have analog sources and adding a sub is very difficult. I needed my tuners back in after listening to streaming on the GAN1 for some time. I purchased the Holo Serene preamp and paired it with the PeachTree GAN400 and a Schitt Yggi+ Less is More DAC. So all of those pieces vs the single modded GAN1. The modded GAN1 was still better than the separates, but the weak link was the GAN400, the other gear is rather amazing. I tried that gear with my CODA #16 and wow.

The GAN400 though allowed me to add my tuners and KEF KC62 sub. This was with the hard to drive Magnepan LRS+ in a small room.

I was not planning to buy the GAN400 again after I recently sold it. But the amps I really want to get for the LRS+ system are more costly that I want to pay today. So I got the GAN400 as a temp measure. The only negative I have with the GAN400 in this system is a slight bit of hardness on the top end. Nothing fatiguing or annoying, just that it is the weak link in this system. If I did not have the need for my analog tuners I would have stayed with the modded GAN1 and sold the KEF KC62 sub. The GAN1 still puts out some good bass minus the sub.

The third GAN amp I had was the LSA Voyager 350. It was also modded by Ric and it then became an much better sounding amp. Overall it was not as strong on bass and felt a little lighter in sound compared to the GAN1 and GAN400 from PeachTree. I would have not considered it for the LRS+.

If my other office gear was not so good I would not sweat using the PeachTree GAn400 with this office system. Though the low price ($1200), low cost of the LRS+ speaker, and the almost excellent sound of the amp are good reasons to just stick with the GAN400.

I should add that the modded GAN1 was very good with the amazing Yamaha NS5000 speakers but only when the volume was turned up higher than expected. That made me think the amp was underpowered for the speakers or the room was too big.
