Recommendations for a Loft, and shops in SF Bay Area?

[catsynth]

Hi there.

I am looking for a speaker system for my loft. Some of the challenges include:
* Aesthetics, needs to fit in my glass/metal/black modernist style (i.e., no big wooden boxes)
* The main area is pretty large (about 17' x 21'), and is open to the other areas as well as the upstairs.
* The rear right speaker will have be on a relatively isolated wall, difficult to reach with wires without looking really lame.

Also, can anyone recommend a good store in SF or the bay area for auditioning/viewing (and preferably without pushy or aggressive sales people)?

Thanks!
