Stereophile boys say you need around 200 watts and good current drive for the babies. That means a big solid state amp if you want the Class A sound as well.
The only one I can think of that would be a reasonable price S/H is a pair of Parasound JC1 monoblocks.
These have the wattage you need and more, but they also have a switch on the back that you can switch to a much higher Class A bias to give you that oh so sweet Class A sound to the upper-mids/highs and a hot heatsinks to boot, but you'll still have the big Class A/B wattage for the bass and lower bass.
And then you can switch it off to lower the bias and power consumption (cooler running) when you just need it for background music.
PS: Zd542, the old fan cooled KSA50 and KSA100 were Class A all the way to clipping. But are under wattage power for these speakers, unless you listen to low to medium levels only and sedate music as well.
