Its best to use the same cable...as a matter of fact, its even better to bi-wire with seperate (but same) cable for each leg (4 cables/side) Cables that have single connection on one end and double (4) connections on the other are not as good.
Is it necessary to use the same cable brand and model for bi-wiring??
I have a pair of Wharfdale Denton 80th Anniversary speakers that can be bi-wired. I have read many pro and cons about bi-wiring improving the sound quality. I still like to give it a shot, but do not want to use an expensive pair of speaker cables to satisfy my curiosity All comments and recommendations welcomed
