Synergistic Research B&W spec series

Also, what is the difference in sound with and without the active shielding activated?

I've been using SR speakers cables with a set of B&W 801 S3 speakers for at least 2yrs I'm very pleased with the results...

I am using a pair of six feet SR B&W Spec Eight Biwire between my B&W 802D and McIntosh MC501 monoblocks. Quite happy with the combination, very clear high, smooth mid and tight bass. But you've got to have the MPC on to achieve a blacker background and a live and natural timber.

I am using an 8 ft pair of spec 7's with my 802N's and am really pleased with them. Great clarity and they take a bit of the brightness out of the presentation. Need to use the MPC.
