I emphatically second Kal's (KR4's) comment just above. Cables are not the answer. However, in this specific case I think that the following comment may be particularly applicable, although for different reasons than were speculated:
The CD player evidently has a tube-based output stage, which presumably includes an output coupling capacitor. The reference to 100K loading strongly suggests that the value of that capacitor is such that there is a substantial rise in output impedance at deep bass frequencies. That will result in a significant deep bass rolloff if the input impedance of the preamp is not high enough. Given the relatively low input impedance of the CP-35, I suspect that effect is at least a significant contributor to the problem, if not entirely responsible.
I would suggest that before making any decisions about how to proceed you first try to borrow or obtain a different CD player, preferably one having a solid state output stage (and therefore presumably a much lower output impedance), and see what kind of deep bass response it provides in your system.

After looking at your system, I wonder if you are getting all the bass the Tylers are capable of producing. Please keep in mind, I think you have a nice system, and just asking questions about synergy.
