The Altecs are quite efficient, so both amps can drive them way too loud if necessary. However they both have they pros and cons, so I'm bit undecided with this matter. Even haven't tried any, I'm pretty sure Hiragas amps even the monster one are suitable for Altecs. However have tried some other SS amps and think that with Altecs are quite demanding speakers in that sense, so perhaps I have to disagree with the french mafia at least a bit..
thanks, my experience with onkens is limited, just listened to a few semi successful boxes. there was lots of hiraga writings in french on subject of onken crossovers and onken aplification but afaik his advice was always low power class A (in fact hiraga 20).

anyway, congratulation for the most interesting system there. is your crossover a proprietary design or there's a schematic somewhere?
