stay away from adcom amps with mac speakers,the adcoms will not bring out the best in them,dont get me wrong adcom makes some fine amps & i own a pair of adcom monoblocks i really like but they are a very bright sounding amp & they wont compliment the ls360's.
if your friend is willing to up the ante about a grand he could score a mcintosh mc500,ive owned a ton of mac & still do & one thing i know for sure is that mac sounds best with other mac gear.
if it was me & i couldnt afford the mc500 then i would go after a krell ksa150 or higher,ive owned three krell amps & all worked excellent with mac speakers,i feel that all the other amps you mentioned will not do them justice.
