There is no simple answer as the whole question of bi wiring is highly controversial. My own advice is to go for one really good pair, like Cardas GRs or GCs or equivalent and a pair of jumpers. If you do bi wire I would go with the dedicated bi wire cables [ one set of connectors on one end and two on the other] rather than 2 different sets. I have bi wired , bi amped and whatever and found that results vary with equipment and your taste.
