speakers for mc452

Need a pair of speakers to complement my future upgrade to mcintosh mc452 and c2600 mcd550 

price range around 8-12k, prefer new, but open to exceptional used 

Mostly classical music, symphony and classical, i like high volume levels 

Room size 18x18 sf

Aesthetics important, prefer piano black 

I have a REL S5 sub as well 

currently own Vienna acoustics mozart grand with ma6600 and mcd550, love the warm mc sound 

i don't know too much about this. but there's a mcintosh dealer in whittier california in business since the 1950's that likes the martin logan speakers.
