I've been using mostly 24/88, 24/96, 24/176 & 24/192 plus a few AIFF, AFF & perhaps less than 10 mps to listen to. I lost my entire audio system in divorce alone with 2,000+ lps, so right now evgerything is digital. Most are from HD Tracks, a few from Linn and my Itunes library. I've never tried any streaming services so have no input. But with the hires files, the R-2R Dac, the THX AAA 789 and the AK's I'm enjoying music and hearing into mixes like I've never been able to before.
