Digital downloads reviews

Not looking for expert reviews but many hi rez downloads do not sound all that great. I would find valuable a review of sound quality not just the music with which I am probably already familiar. Where do you look for reviews on hi rez digital downloads?
The Absolute Sound does a couple to a few each issue under the headings "Jazz and Pop" and "Classical". I'm not aware of anyone who does a lot of them. HDTracks and Acoustic Sounds have best seller lists but I'm not sure that's a good indicator of sound quality.

Someone started a review thread here but it never caught on.

The Hi-Res sites need to get customer reviews set up the way Amazon does. They've been a little slow in getting the Hi-Res ball rolling. I guess we're going to have to be patient a little longer.
