Thanks for posting your listening impressions. I agree with @ghdprentice recommendation to audition a top flight streamer in your system. Between the two brands, any dealer should be able to afford you a in-home audition without any obligation. Keep in mind, Aurender is not ROON compatible yet so there would be a bit of learning curve.
I prefer Aurender’s Conductor App by a mile over ROON in my system. My emphasis is always on SQ (do no harm to digital bits) over a fancy UI. Congrats again on such a beautiful system.
