I've been doing some beta tests with this stuff- and overall it's pretty good. My only complain is that it appears to be a bit "overkill" in terms of size-- but sonically I have no complaints.
The Canare 4S11 speaker cable is decent as far as regular speaker wire is concerned, nothing special. I have my surrounds wired with it and in all honesty could not tell the difference between it and the 12 awg monster they replaced. Before placing it in surround duty I did try it for LCR duty and found I preferred the Nordost cable. FWIW speakers are Paradigm (60's and CC)
