It's never going to be completely apples with apples as I don't have MP3 switched on, but I have a large number of MP3 albums on my Sooloos which I don't have FLAC rips for.

Sooloos, Roon, G series (with LPS upgrade), 800 series (with LPS upgrade), HD621, AC200, Prime and PS, DSPs old and new.

Purdeys, Moke, Leica, 'Blad. Only the best.
