You definately need good amplification with the CLSIIz, as with any good, reveiling speaker. However, the fact that the impedance tends to range from 4 down to 1 ohm (!) makes this all the more important. I have used 2 Gryphon amps (the S100 and the new Antileon Signature) with spectacular results. For tube amps, use one that is designed to perform optimally at low impedance levels, such as the CAT JL series amps. I would recommend an amp that can deliver at least 100 watts into virtually any load - high current!
For bass, you need a very fast, fully enclosed sub or pair of subs. The best results seem to come from the REL Strata III model - not the most expensive or deepest of the RELs, but definately the quickest. I run my CLSs full range (keep the xovers from distorting the sound) and run the subs in parallel via a REC OUT or off of the amplifier taps (unique to REL).
I agree that this is not for "head-banger" music, but is also one of the most technically and musically accurate speakers you will ever hear. It's also pretty neat to look at; especially with mini flood lights mounted behind them (and pointed skyward) to highlight the see-through membrane; real cool!
