Earlier this month began using Roon to play stereo DSD .dsf files, both to Chord Qutest connected via USB to Roon Nucleus in main rig and
elsewhere in house streaming to Bluesound kit.
In my case these have all been rips from my own SACDs.
(I'm ripping these myself using Sonore's free ISO2DSD software with a compatible old Sony Bluray player functioning as the server - can read more about how to do this over at Hifihaven). With the better recordings, enjoying the increased sense of air, especially in my main rig. All things being equal, prefer to acquire the SACD and rip it myself. However, for those SACDs that are either too expensive or otherwise unobtainable, DSD downloads from sites such as Accoustic Sounds might well be a very good option. You've peaked my interest.
