Shadorne is right about 'damping', and in fact its more profound then that- once damping factor exceeds about 20:1 or so, there is no improvement gained. 'Damping factor' is a bit of a misnomer, as it assumes more about the load being inductive than it being an electromechanical device which is powered by the amplifier to any excursion, complete with its own suspension. In the case mentioned, its likely that its not a damping factor issue at all, more likely that there is a problem with the floor, resonance in the front end or something like that. IOW, 'damping factor' is the complex explanation where there are also a number of simpler explanations.
Dcstep, I appreciate that you have not found the right tube amp and so you have had to look at transistors. That does not say however that tubes cannot do the job- even for you- all it does say is that you've not seen that yet. What is important to get here is that the match between the amp and the speaker is critical. The idea that you go with a certain speaker and then find an amp for it is common, but weak. Here's why:

If you use a tube amp with the wrong kind of speaker, you will never hear what that tube amp can do. In the case of the CARs, they are designed for tube amps and if you put a transistor amp on them you won't hear what the speaker will do. I had this pointed out to me in spades when a solid state competitor showed at T.H.E. Show 2 doors down from me with the exact same CARs in his room.
Any time a Voltage paradigm device is used with a Power paradigm device, you will get a tonal anomaly. This is not a conversation about tubes vs transistors BTW. That's just the tip of the iceberg.
