You actually have a well balanced system as it is now. Have you tried upgrading the power cord on the CD player? The CJ gear does not have IEC's if memory serves.
I always felt the PV-12 was very slightly to the dry laid back side. You may not agree. Depends somewhat on the tubes. (I am referring to the CJ stock tubes in my comment.) You could try something a little livelier like a Blue Circle BC3, or a CJ Premier preamp.
A new preamp may require you to also get a separate phono preamp, depending on which one you choose.
You could also go for livelier cables like Siltech.
It is sometimes tough to change speakers. In many ways the system is built around the speakers, since they are the only component which lets you hear/judge your system.
