How loudly the speakers will play isn't solely a function of the power amp you use with the Vandy 2CE Sig's (or the "3" series either). Vandy speakers use a first-order crossover, which is necessary to maintain the phase coherency of the speaker. First-order crossovers have a common characteristic, which is their tendency to somewhat compress the signal when driven to high volume levels. Hence, Vandy speakers (at least the "2" and "3" series) aren't the ideal speaker if you intend to listen at very high, sustained volumes. Having said that, I know from my own experience with Vandy speakers (owner since 1987) that they perform much better with higher power amps. If you will be using the 2CE's in a larger room, or playing them fairly loudly, then I suggest you get a power amp that is rated at 150 wpc RMS and has good dynamic headroom (preferably about 3 db) -- and 200 wpc is advisable. This will rule out at least two of the amps you listed above.
