Speakers for Mac 501's ?

I met an audiophile at a local shop asking for suggestions on speaker synergy.

Any experienced owners who found a musical match ?

I did a quick search and found Aerial and Sonus Faber to be good ?

His room is 15'x 25' with Mac Transport / Mac Dac / Straight into 501's.
same size room, same equipment- love my sonus faber cremonas
I am using JM Lab Alto Utopias--love the combo with MC501's.
I find that Macs and B&W Speakers work well together.
i took my totem mani 2's down to my local macintosh dealer and hooked them up to the 501's and the 1000 watt mono's. both setups were fantastic.
