dis-similar bicables? Why not?

Many Single Bi-wire cables use different gauges and composition for the highs and lows. Also, quite a few folks do this with Kimber 4(xx) and 8(xx).

I used different brand cables exclusively on my Magnepan MG3.3rs. I just made sure they were the same length. The Maggies always sounded best with better cable on the ribbon/midrange. The bass panel liked heavy guage cable..

I would think that with dissimilar cables, you might have a phase shift problem between the woofer & tweeter. But, I can't state that this is a fact. Better minds may be in order here! Happy Tunes

I wonder how much different geometries and dielectrics might affect the velocity of propagation at audio frequencies ? I know that Nordost speaks of a 94% velocity factor, but i don't know how "slow" or "fast" other cables conduct the signal. I know that this might be considered "unimportant" or "insubstantial" by some, but i would still be curious as to numbers. As previously mentioned, my main concern is a phase or time delay between the various frequency ranges.

Bottom line is, if it sounds good to you, that is all that matters. Sean

Sean, I think you're onto something there. When I used nordost red dawn on the newform ribbons it was too much. I think the speed of the ribbons worked against the speed of the cable resulting in extremely zippy notes with little body...I run the acoustic zen satori full range with mapleshade ribbon jumpers. This seems to give the right speed to both the ribbons and cone bass drivers. Interestingly, the virtual dynamics Audition power cord on the amp seems to add a "coherence and correctness to the sound. Is this a result of correct phasing? Or correct velocity? What artifacts have been removed? The point is that if it sounds great single wired, you can listen both ways to see what the cabeling is adding or subtratcing and as Sean says, go with what sounds best. It is possible that dis-similar cables on hybrid speakers can be promblematic.
