Re: I have no problems with what you say, except for...

Clark,

You're right. Nothing ever sounds exactly the same. Not even the same disc played in the morning or at night. Every playback is 100% unique in terms of the environment and the condition of your ears.

I guess what we are trying to figure out is what tweaks actually work in that they always give consistently better performance with them than without. And what tweaks are system dependent rather than system independent.

My point about the WAV files is that if you make a bit perfect copy and can confirm that the WAV files extracted from a CD-R and CD are _100% identical_ (you can check this - and a lot of people who copy CDs don't realize that of they don't figure out the read and write offsets of their drive and use software which can deal with this you will not be making bit perfect copies of your CDs) then the chances of playing both of them from the WAV on your computer and have them sound exactly the same is the same as the chances of playing either one of them twice in a row and having those two plays sound exactly the same. You will not have one _consistently_ sound better than the other. You have removed uncertainty in the source timing, data offsets causing the digital filter windows to actually see different data, etc. The uncertainties you still have are those of timing on the D/A converter and analog distortions from other sources... but these uncertainties are the same regardless of which file you choose.
