I remember reading the "New Methods for Quantifying Sonic Performance" series in the Absolute Sound when it came out.
e.g.

After going through all of the articles I re-ripped all of my 100s of CDs again using dbpoweramp to wav.
I did some tests at the time and thought I heard a difference, but I have no idea if I would hear what I thought I heard if I did it again.
When I do buy HD dowloads I pick wav if the option exists. I have a large NAS so storage size isn't an issue for me.
