while an adcom amp may not be the best match for the 3.6, it's prolly not the best match for the 3.5 either. so, if yure satisfied w/it driving yer 3.5's, i'd at least try it w/the 3.6's prior to getting a gnu amp. ewe may be pleasantly surprised, and the upgrade disease that aflicts us all, may be successfully held at bay - at least for a few days! :>)
i used to drive a pair of 3.5's w/an adcom gfa555, w/satisfactory results. changing over to an electrocompaniet amp, even tho about half the wattage rating, drove the thiels even *better*, prolly cuz the current output is about 4 times that of the adcom. also, imho, electro amps are as good as it gets in solid-state. ok, shameles plug time! ;~) i presently have an electrocompaniet aw100 adwertised f/s here on a-gon for a measley $800 - w/100wpc/190 into 4 ohms, >80 amps current output, i *know* this will work well w/thiels! :>) i *upgraded* to a matched pair of electro amps, so i could wertically bi-amp my present speakers...
