Thanks for your responses, they're very helpful. Hope I can ask a few more questions about the SR15. Are you finding the MQA quality quite good? Is it doing a full unfold? IIRC the usual output is at 88khz/24bit. Also might anyone know of a set of iems that pair well with the SR15. Mostly I'm interested in a wide soundstage. Lastly, are there options for high res music for people who prefer to download? The SR15 seems to have support for Deezer, Groovers+ and Tidal, but it seems like these offer streams only, you can't purchase individual tracks for permanent use. I know of HDtracks and bleep.com. Are there others to try? Thanks very much.
