Hot Rats and KOB sound great on CR. KOB can still be found at a lot of places, don't hesitate on this one since it's the only version on vinyl where the tapes were aligned for the correct speed. I wish I was into vinyl when the 45 rpm KOB was still in print. 
 
Brubeck's Time Out is another great jazz album on CR, though my mono 2eye is pretty nice in itself. A few places still have the CR Time Out for sane prices.
