Well, as opposed to some responses here which don't answer your question, but merely implore you to buy the brand THEY did, I'll give this a shot. The B&W's are great speakers. For the price difference, try to go with the 803 as the extra bass is welcome and they are not too much larger. They are rated at around 89-90db and 8 ohms (but dip to 3 so use the 4 ohm tap on the VT. I also have an ARC VT100 and it will drive these fine. I would avoid the larger 800 speakers as these are bears to drive. The Wilson's are also great speakers and are decently efficient at 89db and 4 ohms nominal are not too difficult to drive, again, just use the 4 ohm tap on the VT. Please note that these are quite different sounding speakers made for different buyers. The Wilson's can be very unforgiving of setup/source,etc,etc. The B&W's are probably easier to live with for mortals...as always, try to listen to them in your own room if at all possible. Not easy with speakers this large though. Good luck!
