Reference 7, 1 kHz 44.1/16 (Distortion is probably noise in the scope)
Metrum Octave, 1 kHz 44.1/16
Reference 7, 5 khz 44.1/16
Metrum Octave, 5 kHz 44.1/16
I have quite a bit of DSD the quality of which I don't find to be that good. A lot of it would have started as PCM in the first place anyway, and if that wasn't well recorded and mastered, then there is no possible benefit IMO.
