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.
To bi-wire or not to bi-wire?
I have a pair of B&W 804 Nautilus speakers. They are currently bi-wired with Kimber 8TC cables. I am going to upgrade the cables and was curious as to whether there is a significant difference in sound with bi-wiring. Most of the cables for sale on Audiogon are not bi-wired. If I stay with the bi-wired cables it narrows the field for some good used cables.
