@mclinnguy "Blues" by Jimi Hendrix sounds great on Qobuz
OP....As I said a bit ago in this thread...maybe it's something else like your switch, ethernet cabling, ethernet filtering and so on? Please tell what your setup is going into the streamer (and DAC).. Room treated? My experience has not been as yours especially after filtering and room treatment, etc. I went from Mac Book to Bluesound to a Lumin T2 to a Lumin X1 (nice and relaxed sound) and to paring up (used) a Grimm MU1/Weiss 501 DAC. Full stop.
The Aurender's W20/A20 are in the same class as the Grimm MU2 (best I have ever had the pleasure of hearing) and many other$. A used Grimm Mu1 is around 8K if your DAC is all set, then please consider one. The mid and high priced Aurender's are grreeeeeat so I would have thought them noticeably better/less fatiguing than the Bluesound(s). Thus I suspect it something else?
A dang fine LampizatOr high end DAC paired with a top Aurender is the best I ever heard but not in my system.
