Very late to the game on this one, but just started streaming on a serious serious service (besides Spotify). Just experienced this vey same issue just tonight for the first time. Heard exactly what was described here: strange mid glair, veiled highs and muffled bass, until about two more tracks went by and then suddenly..pop..air, definition, bass clarity, everything that initially made me fall in love with Qobuz returned. This is after a week of some VERY enjoyable streaming. Could only think it was Qobuz itself sending some compromised packets or something? Hope that’s confirmed…as I’d don’t think it could be my system!
Both disappointed and glad I found this thread, and hope this issue doesn’t come back!
