Something was very wrong with your test procedure,or your sound card/drivers. Via s/pdif, both FLAC and WAV/PCM always give 100% identical (correlation null = -144) comparisons with the original rip file. However, for this to work you do need a sound card that is not being (ahem) "managed" by the operating system... e.g. no Windows kernel sample rate conversion weirdness... By the way, this test actually tells you nothing about what happens when you connect a DAC to the Touch s/pdif... it simply proves what we already know, namely that both wav and flac playback are "bit-perfect" via s/pdif. Noise from the transport can IN THEORY still interfere with the operation of SOME DACs - likewise, jitter and clocking can still be an issue for SOME DACs. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
