I have a lack of depth in "soundstage".

Do you have the means to place your speakers across a corner of the room, I heard a system configured in this manner(using Proac 1SC speakers) and it gave the impression of sounds 30-40 feet behind the speakers(no exaggeration!)
It also seemed to improve imaging and bass response!

"Soundstage"...yeah, right...we all know what you're talking about. I got an email the other day that might help you:

Stop buying pumps and doing useless exercises!
These methods will not work in a million years..

Our pills or patches will do all the work for you. Plus to top it off, if you are not

If you want more information you can contact Elizabeth Delgado....or Sandra Smart, or Deborah H. Potts, or maybe Son Vega...or if none of them get back to you Opal Ziegler might...or Ada Santiago, or even Imogene Page. They all sent the same email to me.....that was yesterday. If none of those work ping me off the list and I'll have about twenty or thirty more names for you by tommorrow!! I gotta stop buying stuff online!

Live music is very dependent on the venue. As you all know, some halls are better than others. Where you sit will have some influence as well.

Cabling can make a big difference in soundstaging I've found. Especially speaker cable. But more than that the speaker positioning as the folks above have pointed out. If you have your TV between your speakers as I do then try moving it a foot or two behind the front plane of you speakers as I have. Makes a big difference.

your b&w's need more power. the audio note is a great amp, but is a better match with a more sensitive speaker. the b&w's would open up big time(front to back)with a tube integrated from arc or cj.....the audio note would match up better with speakers such as the meadowlarks,etc. this is a tough choice, but either way the improvements would be dramatic.

The biggest impact on soundstage is speaker placement. Speakers which are placed to close to the wall will possess increased bass, but they will surrender soundstage. Moving the speakers out from the wall will benefit soundstage depth but there will be give-and-take with your bass response.

A couple of things which might be of benefit are Robert Harley's book "The Complete Guide to Highend Audio," Laura Deerborn's book "Good Sound," or you might try http://www.rivesaudio.com

All three will deals with your questions from one angle or another.
