i had a cary slp98 pre for a while, & it was wery nice - better than the magnum version of the rogue 99. customer service is also excellent. but, my current melos music director is in another league altogether than the cary.
re: the cary amp, i haven't heard it, tho i've heard folks who enjoy driving proacs w/it. my opinion is that the proacs wood do better w/as much power as ewe can give 'em, so i'd tink the mac amp wood be a better match.
