When I was at Lone Star Audio Fest, Joshua Miles of JWM Acoustics recommended this Album by Ray Brown. It's a dual 45RPM LP.
I bought it and can't argue with Josh's recommendation. Especially if you like jazz.
Your C-11 does seem a bit faded. Maybe try some furniture cleaner/polish to see if it helps.
Here's a pic of my C-11 on top of the TFM-24. Both are black, but the TFM-24 has a bit more gloss.
