@car123 Your impressions of SU6 allign with my presumptions of what I'd have heard if I had cared to even try my Singxer SU6. You do owe it further burn in just to be sure. Trying out LKS would give you one more point of reference. Your usb experience not surprising in least, I'd bet on many usb renderers beating out server usb. Can't give you info on good one for less money than Phoenix, not up to date here.
As for the NON-CONTROVERSY of measurements vs listening in rating 005. Non-controversial in the sense the objectivist vs subjectivist divide only continues into the infernal. There have actually been some pretty informative arguments on this subject at this forum, believe everything that could ever be said in regard to this issue has been addressed in this forum.
I only know 005 will continue to have exact same sound as prior to ASR review. Jimbo addressed issue of O vs. S in stating 005 tuned by listening, no misdirection there. I haven't looked at 005 marketing measurements vs ASR, if they are not accurate he should be called out on that.
Going at it big time over this one at ASR, 11 pages and growing. Lots of people over there referring to some bashing of ASR and objectivists from this forum. There are some defenders of subjectivism on the thread.
