Actually I always go back to these few when I am trying new equipment and for the joy of it all. My problem is they are so few. I can hum them in my sleep. I agree that often it is a catch 22 situation for me, as well, as I continue to look for really good recordings. I used to try and get the " records to die 4" in the jazz, classical and rock category. After the first 5 or so arrived, I quickly realized that I did not like 3 out of the 5. Well recorded, just did not like the music. When I really like the music, but the recording is not great, I turn the lights off, see the glow of 12 tubes from my amp, and things always sound and feel better.
