I have been using Tidal HiFi ($19.99 plan) for years now and recently got a new 2 channel system and wanted to try something different because I wasn't blown away by the sound with Tidal. I now have a Prima Luna Evo 400 integrated amp and GoldenEar Triton One.R speakers. My source is a Bluesound Node streaming over WiFi and then through Music Fidelity MX-DAC (lovely sounding and affordable btw). I have always been suspicious of MQA because I could never hear a difference with it on or off and don't understand the unfolding process. I am blown away by the difference Qobuz makes ($12.99 plan). The soundstage opened up and the mid-bass and bass is much stronger. I had to dial back the subwoofer sections of my tower speakers because the bottom end was so much stronger. I think the sound is more balanced now and it sounds stunning. As far as the interface I think they both leave something to be desired. I would love to see more options for sorting songs within favorites and playlists. Also I found that all of my music library was licensed to stream with Qobuz when many songs no longer were with Tidal.
My 2 cents. Thanks, James.
