I did two downloads from the Pentatone (Classical) label from a different site. The downloads did indeed take forever and then weren’t pristine, with a few brief dropouts. I tried this to compare the same recordings, which I have in SACD. My Oppo 105 can output the DSD layer of SACD over HDMI to the HDMI of my Bryston DAC3 (DSD 64). I think the downloads were 128. I couldn’t sonically distinguish any difference between the two resolutions, and given the hassles of the downloads I’ve just stuck to accessing my DSD from SACD as described above
