B&W vs Von Schweikert house sound?

I am more familiar with the VR4 JR (I own two pair) than the VSA speakers you listed. You have listed quite a range of VSA speakers. While there may be a house sound, you will hear differences across this group in the attributes you listed. Bass tends to be fairly quick for all the VSA speakers listed, but there is generally more impact and abiity to go lower with the VR5 than the VR4.
I find the high end of the Von Schweikert to be less fatiguing than the B&W speakers and somewhat more forgiving of recording quality. The Von Schweikert speakers also seem to be less amp dependent in achieving optimum sound than the B&W speakers you listed. It is difficult for me to make detailed comparisons because of differences in room acoustics, associated equipment and break-in when I have heard these speakers.
You might find an owner in the NYC/LI area willing to provide a demo of Von Schweikert speakers. Try posting in the Von Schweikert forum on Audiocircle.com if you want to pursue this possibility.

If you look at the multitude of threads that are basically people looking to "fix" their B&W issues with a [insert cable, amp, pre-amp, new speaker, etc.] it should tell you something. To my ears they sound good at first but after just a few minutes the sound and lack of musicality wear thin. I have even seen a dealer sneak a sub into demos of his B&Ws.

VSAs in comparison have a smoother but delicate top end, better sound stage, and they dig way deeper with good authority on bass. To me the VSA are better from stem to stern and are pretty great options at their price points. In a 15X18 space the 4JR would be a good option.

I think Maineiac nailed it, plus he has great taste in women. You'll be happy with any pair of Von Schweikerts for many years. The VR-4Sr. certainly helped me get off the crazy upgrade highway, and I owned probably 20 high-end speakers before settling on Von Schweikert. The VR-4Jr. is probably one of the best deals in audio.

9rw: Is he married to your sister?

Maineac, I've read alot about the Jr, and what a great bargain it is. But does it really compare to the 803/2D, or the VSA 4SR/mkii and VSA 5HSE/SE?

I am guessing that 9rw is referring to the fact that my plasma is showing Carrie Underwood in my system pictures.

I have not heard the VSA 5HSE/SE. I am purely guessing that because of your room size that the 4SR might be a bit overpowering on the bass and they are just physically big speakers too. I would call Albert to discuss.

I did extensive demos of B&W 803N (not D) as well as thiel, sonus faber, usher, etc. and could never get comfortable and enjoy what I was hearing. The instant I heard VSA4JR it was a done deal. The 3D capability of VSA is incredible. I am not sure if there are many dealers left because of the change in the sales model a year or two ago but you should hear the VSA for yourself if at all possible.

If you like the B&W sound and flavor then moving up and across lines may be what you need. It just never worked for me.
