I gave the PeachTree GAN400 a nice long trial run on my office Magnepan LRS+. I used a Holo Audio Serene preamp (amazing) and my trusty old Benchmark DAC3B.
The GAN400 drove the LRS+ very well. Almost as good as my CODA #16. However, the CODA #16 had much more engaging sound to it. If the GAN400 is 8.5/10 then the CODA was a 10/10. I used the CODA with a Benchmark LA4 preamp and DAC3B. However, those components were moved to my main rig so the GAN400 was purchased.
I put the Peachtree GAN1 (modded by EVS) back into the LRS+. It lacks a bit of power compared to the GAN400. I also need to move the volume dial on ROON higher than when using my preamps. However, it is a very engaging sound. Like the CODA #16 but with less deep power. This is tolerable with the LRS+ speakers and my small office.
The PeachTree GAN400 is being returned. It is good but the modded GAN1 is great, even if it could use a small boost in power for the LRS+. I got to figure out how to connect my KEF KC62 sub to the GAN1. It so much easier to hook up the sub when using a preamp like the LA4 or Serene.
