Hi, I am considering buying a DM-41 DAB, pairing them with Q Acoustics 3020s or Dali Spektor 2s. I intend to connect it to my TV and PS4 via the optical inputs. I was blown away by the sound quality when I demoed the CD player. However, I don't own as many CDs as I'd like and I mainly listen to music via Spotify Premium. I was much less impressed with the sound quality when I listened to Spotify Premium, streamed at 320kbps, through my mobile phone's 3.5mm output (Nokia 8) into the RCA input of the Denon. I understand that listening to a CD is always going to be the better option in terms of sound quality but I was shocked at just how much better it was. Having read around about why the quality was likely so poor when listening from my phone I think the rate limiting factor here is likely my phones DAC. I thought that one way around this would be to use a Chromecast Audio via optical input to the DM-41. Hopefully this would be much better, using the internal DAC within the Denon. Does anybody know whether the internal DAC of the DM-41 is actually of decent quality?
