9 gauge vs 12 gauge Jumper of same brand cable

Hi, I am contemplating of getting same brand cable's Jumper to replace the stock jumper of my spkr. My spkr cable is Analysis Plus Oval 9 (9 gauge ). I am wondering should I go for AP Oval 12-jumper(12 gauge) which is not as THICK and easier to attach to spkr binding post , or get
the Oval 9-Jumper (9 gauge)? Would there be any significant sonic differences between using them ?? (would Oval 9 jumper sounding better than Oval 12 ? especially on Bass region ???)
Your opinion,explaination and suggestions is highly appreciated and thanks in advance

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)

Although Newbee made a good point, the strands used in both Oval 9 and 12 are different. In this case, it would affect the sound more than total AWG for impedance matching. If you insist spend the money and buy the jumper cable, I would definitely go with the Oval 9s.

Thanks S23chang.
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
Thanks
