Single-wire spades from amp to biwire spkr posts?

Mitch--thanks for all that info! I do have the Cardas jumpers,
so I'll try those. I know that there are several discussions here about how to orient the jumpers, and with my former Von Schwiekert speakers I had better results with the stacked spades on the LF terminal, contrary to most things I've read (clearer, less foggy bass; highs were fine and liquid with that nice VSR Revelator tweeter). The problem is I have a long run of speaker cable (> 20 feet), so new cables are expensive, and my Cardas are well broken in (I've had them for several years, and I bought them new) and I hate to let them go. I'll take a big loss if I sell them. So I'll see what I hear with the jumpers. Thanks again to Mitch and everyone else who chimed in here.

Good luck with your trial. If you like the sound but do not like stacking spades, I would bet Cardas would be happy to reterminate one end of your jumpers with bananas.

Ive actually been thinking on this, how can a speaker be truely internally bi wired? This would mean they would have to touch on the inside of the posts, this would result in cross talk just the same as if you used jumpers on the outside of dual posts. This is why I dont get bi wire, it seams useless. Even with a standard bi wire cable(2 one side, 4 on the other) on dual posts, they are still touching each other at the amp, making cross talk(would take a little longer to reach the giant loop I guess, I would actually think that would make it even more un acurate of a sound(doesnt current travel both ways?). The only advantage I can see is bi amping, and that can lead to problems as well, such as unequal/unblanced signals. You would definatley want something like a bryston 8bsst or 4 channel amp to take full advantage of bi amping.Any opinions on this.

Yep, it is conceptually messy as long as thing come together at any point, but I'm no electrical engineer here. I was told to avoid internal biwired cables. Any thoughts? Thanks.

There are multiple factors, such as how the crossover boards are implemented within the speaker, how the bi-wire cables are set up, and others. Some internally bi-wired cables simply split the number of wires between LF and MF/HF, while others double the wires inside of their bi-wired cables, like with my Purist Venustas. Other manufacturers offer double bi-wire cables that have two separate runs terminated together at the amp end, and some do that while using different gauge wires for LF than for MF/HF.
