Slbenz, great review and comparison to the MF X10v3. Did your X10v3 include the MF XPSUv3 outboard power supply as well? I have this, along with Revelation Audio Lab umbilical PC and Signal Cable Silver Resolution PC. I've been reasonably satisfied with this set-up between pre/pro and amps; but always wondered about the Yaqin. It sounded like more of an improvement when I added the buffer in front of my old Outlaw monoblocks. Since upgrading to Channel Island D-200's, there doesn't appear to be as much of a difference. I'm wondering if the Yaqin would kick it up a notch ... comments?
