Blindjim,
FWIW, I don't have any spikes anywhere in my system. My problem had to do with muddy bass that affected the overall sound. The bamboo boards under the speakers with a little blutack between them made a huge positive difference with that problem and cleanup the midrange and the treble too. I don't know if that was an artifact - I.E. cleaner bass affects the whole spectrum by allowing the information in the upper registers to come forward and no longer be obscured by low frequency resonance? So for me, the bass may be tipped up a bit as a result of isolating them from the floor, but certainly not in a bad way for sure.
Speaking of tipping, my speakers aren't that tall and I have wooden shims under the bamboo boards tilting the speakers up about 10 degrees which helps with the imaging a lot, and maybe improves the phase between the tweeter and mid/woofer??? In any case, tipping 100lb speakers without substantial and well secured spikes dedicated for that purpose might be ill advised!
Finally, putting a large beechwood block under my CDP made a huge and silly good difference in the sound of CDs. Much more balanced and analog with no more sibilance or digital nasties. I fooled around with different methods to support the CDP on the wood platform including small hardwood blocks directly under the case and found that I liked the stock feet the best. The hardwood blocks increased the resolution but reduced the bass too much for my taste, "tipping" the overall sound up as you say.
You will just have to try different configurations to see what you like best. I am definitely sold on the value of big blocks of wood for various application in hifi systems. One of the cheapest and most effective tweaks I have found by far.
