Audio Refinement Complete owners: please advise

I would like to hear from other ARC owners RE: what speakers they are driving w/ this amp. I have received very conflicting suggestions and am not sure how to proceed. Can ARC handle large floor-standers such as Paradigm Ref. Studio 100V2, or am I confined to monitors with thsi integrated? My room is 17x28 w/ 15 ft. ceilings. I listen to acoustic Jazz, 60's/70/s rock, singer- songwriters (Hiatt, Thompson, Prine, etc.), some folk and country. Like some volume but not ear-bleed levels. I'd appreciate any suggestions. Thanks!
