Interesting. My hearing stops at 14 khz and unfortunately I seem not being able to register a difference in SQ above cd-quality level (or actually less). But I will try again to A/B-test the analog signal from a bluesound directly to the amp with the digital signal from the same bluesound passing a HQ dac, at exatly the same level (not easy) and with not more than one second changing time.
Maybe the problem is that I only use the standard free ethernet cable from the router to the bluesound? And the router receives the signal through 4G.
