I didn't know so many people would be interested so here is why mapleshade doesn't do biwire bundles, its not much We don't make bundled-together bi-wire sets because bundling the two runs of wire always degrades the sound, both for our wires and other manufacturers. The two runs should always be separated by at least a foot. Other manufacturers don't mention the inherent degradation in bundling because they know people like the convenience. There's one more important principle in bi-wiring: the better the wire, the less benefit there is to bi-wiring. We find a nice benefit in bi-wiring with our Golden Helix (single helix) cable; when you get to our Golden Double Helix, there is almost no benefit and we recommend that you not spend the extra money. Our customers' experience is that our Double Helix single-wired almost always sounds better than any competing wires (say under $2000) that are bi-wired. One other recommendation: when single-wiring, don't use the speaker manufacturer's brass plate jumper. They sound surprisingly bad. For $20 we'll custom make you a set of jumpers from the same ultra-thin ribbon conductor we use in our $1500 Omega Mikro speaker cables. You'll be startled at the difference a good jumper makes, even though it's only 3" long.If you have any other questions, call me at 301 627 6350.
