I voted for the 5% spin, but only for DVD-A / SACD discs where I don`t have a choice.
For everything else, I spin only to rip. But I rip using Exact Audio Copy to straight 16/44.1 .WAV`s (plus companion highest bitrate VBR MP3`s for the iPods and remote players).
I then use a PC with an M-Audio soundcard to play back the .WAV files, but upsampled via FooBar 2000 to 16/88.2 before feeding the 568. Sound quality is superior to any CD device I`ve ever used or auditioned.
Convenience and Quality, win-win.
