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 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.





AGD is decent a little rolled off at the top. 
The type of transistors just a gimmick. If you want the best stuff for the money I like Modwright. Unlimited budget Audionet.

I am using a pair of AGD Tempo (bi-amping). I compared the AGD's to the Atmasphere monos and to a Pass XA-25. 

Both the Pass and the Atmasphere's are darker than the AGD's in my system (Bakert Rhythm pre and Fyne F1-8 speakers). The AGD's are smooth, detailed, and balanced - again in my system and to my ears. If you have speakers that are a little bright you might prefer the Atmasphere monos which are also excellent.



Always appreciate your thorough assessments. I have a Voyager and love it. I also have a Ric Schultz EVS 1200 and love it too

The amps I want to hear is the Daniel Hertz Maria "amps". It is like the PeachTree GAN1, but maybe not GAN. It also has an A2D convertor for analog sources. I also believe a sub is easy to hook up to it. No remote control though.

I am looking for forward to what the future will bring with Peachtree GAN1 like pieces. Eliminating so many items makes sense to me in many ways other than just cost.

BTW - when I owned the LSA Voyager 350 it was with the older KEF LS50 and the Thiel CS3.7. I forgot I had not upgraded to LS50 Meta yet. I sold the Voyager because my CODA #8 that I owned at that time was stronger on the bass for the hard to drive Thiel CS3.7. Wish I had not sold the CODA #8, it is perfect for the LRS+.

As I post this comment, I am listening to some Earth, Wind, and Fire on the LRS+ and PeachTree GAN1 and each time I hear this MODDED "amp" I am shocked at how good it sounds. Just beautiful.
