I pulled the trigger on the Peachtree Carina GaN. It checks the most boxes and I could get a new unit for less than the others used. The factory is actually a few miles from my home so i was able to pick it up directly from the factory. So far it is a huge jump forward in transparency, control and dynamics. I changed my dac, my preamp and amp all at once so it is hard to say where the biggest change is coming from but i think my particular tube preamp was softening everything too much for the Logans. I purchased the pream/amp combo to tame the top end of the Klipsch RF-7 i was running at the time but with the Ethos the Peachtree is a much better pairing. I have a dac, preamp and amp to sell if anyone is interested. The preamp (JMA Peach II) gets rave reviews on the Klipsch forum if anyone has horn speakers as well.
