Wow. I just can't believe you are not getting deep bass with the equipment listed above. A tube player, NAD is if anything a bit TOO heavy in the bass, high end cables and a three way speaker? Maybe Bob's got a good idea with the power issue.
Only other main thing I can think of is component isolation, if you haven't done so already. I find the most solid and extedned bass comes from rigid, spiked islolation platforms. Put each on its own platform if you can. I think Needle Doctor has an Apollo brand wall shelf for turntables, but it may work just fine for cds and amps too.
For speakers obviously Target stands are a good choice, however I heard from someone that field point arrowheads from an archery store are a good cheap alternative. (place three per speaker in a triangle formation, one on the front edge, two on the back corners, spikes pointing UPWARD) You may already know all this already but in any case good luck :^)
