Yes, I have the SA-1, A90, Liquid Plat, A50s, Schiit Magnius, Gehessli 2.5, THX 887, 789, and I have the Gustard on the way. Probably going to get the Jot2 soon as well. Just sold the Schiit Mjolnir.
While I think SoundNews is a nice guy its his subjective review, he was telling people the Susvara was turning off his 789 and A90 because it was drawing so much power which I find very hard to believe unless he has some wiring problems in house. The A90 pushes the Susvara just fine, 789 and 887 do OK. He was always saying the 888 by SMLS was super powerful because it was 12W into 16ohm's without noting the drop off at 32Ohm that matches it to the A90. He's like Z-Reviews, I appreciate his content but some things I take with a grain of salt.
The other post is interesting, I will review, from what I can tell the Burson only does 4w into 32ohm's, which is 2w behind most other AMPs. This guy measured it in Volts too, IDK why he didn't bother to convert to Watts for us laymen. Now I need to figure out the AMP's to get the Watts, maybe I am missing something, still reading it.
