Chess, that woke me up.
I haven't tried with the active omnis. I tried with the M100s and M2s. As I reported when I tried, I found peaks to be 1 dB higher with Tidal HD. That was it. I only checked the peaks with an SPL meter because I thought Tidal as louder but couldn't be sure. I found no difference in soundstage, imaging or fidelity. I am using Firestick 4K via HDMI into my Onk.
I've also tried Amazon HD in 24-bit/96KHz. No difference that I could detect compared to Spotify Premium.
My problem isn't with Spotify. My problem is with Netflix. Why can't I get DTS HD MA quality sound with Netflix? WTF is going on? It sounds like Netflix is messing with the SQ to preserve bandwidth and maybe server space.
