Combining different speaker cables for bi-wiring?


After spending the past few weeks trying different types of speaker cables with my system, I narrow down my choice to two brands of cables but I couldn’t choose on more than another.
The first cable I liked was giving all the details and dynamics I was looking for the highs and mids, but was lacking punch and solidity for the bass.
The second one I picked was giving me all the punch and fullness in the lows, but was too bright in the high frequencies.
Should I bi-wire my speakers using the first type of cable to drive the highs and the second type of cable to drive the lows?
Is that a common thing to do?
Would that affect timing and pacing between treble and bass?
Thanks for helping.

It actually makes more sense than using the same cable. In fact some people don't even use the same amp (bi-amping). Some cables work better than others for certain applications.
Since the high and low frequency drivers are completely different devices, each with its own sonic character, connecting them with different wire is of no concern.
I recently had a bi-wire set-up with a pair of CRL/FIM cables on the bottom and a pair of Virtual Dynamics Master 2.0 cables on the top. While to me the sound was fine, it wasn't what I was quite expecting from bi-wiring. The sonics of each cable were clearly audible and as Davemitchell points out the set-up was somewhat non-coherent.

In the end I'm looking for a one brand solution to try out. However if I had my druthers I would bi-amp, with a tube amp for the top end and a solid state for the low end. I think bi-amping is a better solution than bi-wiring.
open the amp and make sure your speaker cable is the same brand of cables used inside.
If you prefer the frequency characteristics of the different cables it makes sense to use them where they sound best. Some manufacturers use different wire gauges or materials in their cables meant for internal biwire to take advantage of those characteristics. You found them on your own.
