I want to apologize for asking so many questions, but the members on this site are full of knowlege when it comes to HT.(I love it!) Anyway, I have a B&K REF 7250(200x5) running my fronts which are Paradigm Monitor 7 V.4. I have read conflicting reports about biwire setups. Some say it really opens up the sound and some say it does very little and its not worth it. I am sure it has been discussed at nauseum on this site, but I wanted to give it a try. Should I? And if so, can I use two different brands of speaker cable? I am currently using Cobalt speaker cable. I also have a pair of Audioquest Type 4 Hyperlitz speaker cables. If I can use both brands my next question is how to hook up. My Cobalt cables are terminated with locking bananas and the the Audioquest are terminated with spades. Can I biwire when each set of speaker cable is terminated different from each other?
