What speakers work well against a wall

@scottwsmith, If you're speakers are going to be up situated in the corners of the room, the Klipschorns work very well - http://www.klipsch.com.au/products/klipschorn-floorstanding-speaker
I'd also 2nd the AN speakers, especially if partnered with AN gear.

I have a pair of Zu Def 4s in my living room and a pair of Celestion SL700s that sound great when positioned against the wall.

In addition to the many other recommendations, Van Schweikert VR33 and VR35 are designed to be against the wall. 

You will never get “great soundstage depth” with the speaker next to the wall.

Don, normally I'd agree, but things seem to have changed a bit.  I have Vandersteen Quatro's and they set them up in the very corner of the room and I'm getting great staging.  Very realistic.  It's all rooms and system dependent.  

A simple thought experiment is the question, "Would I expect a violinist, a pianist, or even a vocalist to sound good from that position? The answer is NO.

And another one, "Would any knowledgeable recording engineer ever record such instruments/performers in that location? The answer is NO.

So why would we expect loudspeakers to be at their very best in a corner or against the front wall?
