Best sounding cd in your collection

I have heard most of the recommendations on here and agree they are all excellent recordings. Thought I would add one that most people probably wouldn't think of, or ever hear. It is Deborah Allen-Delta Dreamland. Overall it is an outstanding recording, but the part that I like and use is, at the very beginning of the title track, it begins with crickets chirping, it then blends/begins with the unique sound of a steel guitar. This is where you can actually use it to discern subtle differences in interconnects, wire, or anything else where you really need a high dose of something to audibly hear differences. If your system has any "graininess" or any other problems you may be trying to tame this is a disc you can use, or use it while evaluating a system to see how "real" it can sound. You should be able to get this for cheap as it has not reached "Audiphool Status".

New Air release...wow...talk about a recording...simply world class my friends...comes out 3/5 in the states...but I already have it!

Side By Side, Itzak Pearlman and Ray Brown. Fabulous recording, although Itzak shouldn't quit his day job to play jazz.

Duke's Big Four by Duke Ellington (what other Duke is there?)on Pablo is also a really great recording. They really got the kick-drum slam on this one.

I picked up Beck "Sea Changes" yesterday based on the recommendations above...and it's fabulous.

A few other which sound great to me:

Knopfler - Shangri-la
Alice in Chains - unplugged
Tool - Undertow
