How much is about the recording

Big deal to me. Fortunate to have an acoustically treated dedicated listening room. Figured out the setup. Now it's all about the recording quality. I grade every album I hear A,B,C,D based solely on sound quality.

In my collection I'm hearing about 10% class A, 50% class B, 30% class C, and 10% class D.

The key is to get the music you like to sound as good as it can. If you take your system too far in one direction, you'll end up with 3 CDs that sound extremely good and everything else will sound terrible.

Seriously?
what direction would that be?

if it sounds great with one recording, then it should sound great with 90% of them.
Or maybe my system is “not resolving enough”?

@tomcarr +1, utilizing that same grading system as I am culling 2,000 albums down to hopefully 800-1,000 and have to say that I am coming up with about the same #s you have. Enjoy the music
