The short lenght of the cable involved would negate any differences due to the differences in gauge. I would just use the 12 gauge.

I had such a setup a few years back. I let the dealer talk me into the '12' jumpers / along with the '9' wires.---I listened for 14/18 mos.---Then I picked up another set of '9's with bananas to go with the spade version, Together;-----WOW----. Thought I had Vahalla wires. (Have to exaggerate to make the point)
Do you think I should go for Bi-wirng with Bi-Oval 9(same cable geometry as my Oval 9 ,in double run biwire configuration/ 4 connecters on spkr end,2 on the Amp end )?
I would appreciate your(and other reader)opinion and suggestion ;in a way to get reassurance that Bi-wire is the way to go(despite of some downsides such as less/leaner Bass,less coherent ect as some have reported )
Thanks in advance
The result will vary from amp/speaker matching.
We did an experiment and got different result.
Using same pair of bi-wire speaker:
Setup A - Stock brass plate jumper
Setup B - Bi-wire cable
Setup C - 3rd party jumper cable
Setup D - Two runs of identical single run cable
We have tested with 4 different amps and got mixed results
All concluded that setup A is the worst sounding with all 4 amps.
Setup B, C, and D are very similar
In some amps, setup D works the best. More clear, transparent. Improvement in low frequency.
Almost no difference between B and C
This is subjective test with our setups and systems.
Although it is not the most scientific way, it gives listener a general idea about bi-wiring.
Thanks again ,S23chang. for such illustrative and helpful informations.
On setup D - is it 2-pair of identical cable with stacking up the spades on both end with the jumper remained in place ? or having the 4 spades connected to Upper and Lower spkr binding post / while only 2 spades connected to Amp end (jumper removed)
I really need your confirmation ,please
