Dev, I and Suteetat were referring to the audible difference, if any, between 33.3333 (I don't recall how many decimal places Suteetat proposed) and 33.3334, or the like. The software itself (the recording and mastering process) is not accurate to that level. Whether one can hear such a speed difference, if the speed is constant over time, is open to debate. I happen to think even you would not hear it, but perhaps you would. However, the main point of my response to Suteetat was to say that it is not so much super accurate 33 and one-third rpm as it is speed constancy over even small time intervals, i.e., not "average" speed, that is of prime importance in assessing a turntable. And that is only my opinion, not necessarily gospel.
