Marco - let's summarise where we are: 1) wav vs flac via spdif = identical 2) wav vs flac via analogue = identical
So let's move on... to your bigger question. In normal playback, what are the effects of the SB clock drift and the design of the DAC and final analogue stage? To answer this, we need to do a different test. For this we need to compare in ADM an original WAV rip from a CD with a recording of playback from the analogue outputs of the SB. To eliminate errors in the recording process we again need to lock the ADC to the spdif so that both ADC and SB are running from the same (SB) clock. However this will not eliminate any clock drift between the original recording and the SB clock. To be clear, this is as close as we can get to comparing exactly what was written to the CD vs what is coming out of the SB DAC and will tell us how accurate the DAC is in retrieving the original music. Any errors will caused by one of two things: 1) frequency/phase response errors in the analogue output stage of the DAC 2) clock drift (sample rate) errors between the clock used to create the CD and the clock in the SB This is a very hard test - it is brutal.
