dis-similar bicables? Why not?

I've been using NBS Statement speaker cables, but they are not bicables. (between a Pass amp and Revel Studios) Of course the speakers are setup to allow biwiring (and its recommended by Revel). I didn't want to spend another $3K to bicable, so decided to try using some Tara Labs Decades for the bass. I felt the bass is not as important, and removing the bass from the treble cabling might be beneficial. Results: I think it sounds better. I think the highs are a little more detailed. I'll listen for a wekk or two and then go back to listen again. Anyone out there try this?

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
