I'll try using Conductor as a DAC for Mytek (it has an analog input) and vice versa to see if it's the USB module that rolls off the treble in Conductor or the amp itself. As stated earlier, when listening to WA2 with Conductor as DAC it seemed more rolled off than with other DAC's, so that made me suspicious. Will try more and report back to base, haha.
I'm very sensitive to hot treble, but Taurus MKI has great hf extension without being sibilant – absolutely. When I say brighter, I do not mean sibilant and harsh, it is just a relative reference to the lad who wanted my opinion. Also, the SE mode in MKI seems smoother, whereas BAL is clearer and faster. I preferred BAL for electronic music, and SE for (most) other types of music. Ironically, If you read the first pages of the Auralic owner's unite thread, you'll see ardilla stating that Taurus is bright, and me defending against it, haha.
