Speaker cable suggestions


My newly put together system is Plinius 8200 mkII integrated driving Joseph Audio RM22si signature speakers (Full system viewable under my virtual system). Current speaker cable is 6' Kimber 4TC biwired (two completely separate runs).

Problem is, current cable is too short for my setup. I need at least 8', and want 10' or 12' to have some slack just in case. Two questions:

1. Plinius has two separate sets of binding posts for use with biwiring. I like the idea of two separate cable runs, versus those that are joined together at 2 leads at the amp end. Is this just in my head, or is it true I will get better sound from two isolated cable pairs, each with their own dedicated binding post?

2. Can you recommend a cable for my setup. I would like to do this on the cheap (<$200 used), but will consider a little more if people feel a huge improvement to my system can be had.

Thanks,
Matt.

You can get a better sound with single-wire and decent low-inductance jumpers, and it will cost less. Most reviewers are shying away from biwire now.

My theory is that the reason that biwire caught on so strongly was that a few speakers actually benefitted from it and the others sounded better because the factory jumpers were such crap.
I also have the Plinius 8200 Mk II integ. Amp. with some
Infinity intermezzo 4.1t speakers. I'm thinking of getting
Audience cables.
