I'm running biwire Apex between VAC 300.1 and VSA VR-7SE with great success. As mentioned above, this cable just does everything very well.
Also recently discovered the D-3 digital cable that Ted told me should sell for a lot more than they sell it for. He is correct - in my system it easily bested an Acrolink digital cable costing twice as much. I have an all SR system, with Hologram D pcs on the digital components, so to be fair, I would be pretty surprised if ANY cable could out-perform the D-3 in my application. The synergism is very real and I'm very happy.
