ryllau, i fergot to add - if yer really serious about wanting to buy an amp yust for break-in purposes, the electro will be better than the adcom 555, even tho the 555 has more watts. the electro has a *lot* more current output - about 4 times the output. i have a pair of 555's bridged, driving my 95bd/1w/1m vmps subs, so there's no issue here, but i have a pair of thiel 3.5's in the kitchen system. but, it used to be in the main system, and was 1st driven by one of the adcoms, then by an electro aw75. the thiel 3.5 is a difficult load for an amp, & the electro aw75, at only 75wpc/140@4ohms, worked *much* better than the adcom. that amp put out >60 amps current...
