if ya wanna have a combo h-t/audio system, get a preamp that has a default signal processor input - this allows a h-t processor to be plugged-in, and when ya select that imnput on the preamp, it defaults all controls to the processor, allowing volume, etc, to be controlled by the processor. when listening to audio, none of the processor electronics is in the signal path. linn, adcom, vtl, & sonic frontiers all have pre's w/this feature. cuz i like tubed pre's, i'd suggest trying a sonic frontiers - tubed, but wery neutral, which ya prolly will need w/a c-j amp.
if ya like the electrostatic sound, check out the newform research r645 - the other's ya mentioned won't rock or do h-t too well - not enuff dynamics. the r645, @ 91db/1 watt, should be ok. check out their www, & the user reviews on audioreview...
