Hey all, I've been considering the following for my TR-X00 Ebony, possibly just an Amp hooked up to my Xonar STX as that would be cheaper and "okay" I believe. Gustard H10 Asgard 2 Magni 3 NFB-11.28 R2R-11 JDSLabs O2 Aune X7S Lyr 3 The cheaper the better of course, but even with all of the reviews I've seen and read, it's nothing but mixed reviews. Some even say the Grace m9XX is the best, while other say it's not. Thoughts? The Xonar STX is really crippling the potential of these headphones and I'd like to change that. Thanks a bunch.
