I have an MHDT labs Steeplechase 2 for my mac and a Kora Hermes, also tube output, that I absolutely love, for everything else.
I have had less than stellar results with the Schitt gear
If you ever looked under the hood of an Audio Mirror you wouldn't buy it.
The Kora is built by French Aerospace engineers and it looks and sounds it.
I know a lot of people like Audio Mirror, a lot of people drink Budweiser too...
Best of luck!!
