I did some testing over the weekend. Not really done yet as I appear to have opened a can of worms. Thoughts appreciated. Feel free to comment here and on the blog; I'd like to collect thoughts there but don't forgot to post here too.

I found some anomalies when ripping. I used J. River, EAC, 4 drives, and 6 rips. I found pitch variance in a sample from the ripped wav; filesize were the same down to the byte.
