Power Cable for CDP

Hi all. For the last 2 years I’ve been using Oyaide Tunami 2 power cables on amps, CDP and power distributor. Anyone who knows these knows they they are an outstanding 10AWG OCC virgin copper cable. Sound can be best described as detailed, lush and FAT. Conceptually I get the need to feed a hi power amplifier with as much power as you can; usually only achievable with a heavy gauge power cable.

I’m considering using a lighter gauge cable (13AWG) for source and wondering if anyone has any experience in mixing cable gauges depending on equipment connected to the cable? Am I likely to get more speed, air, instrument separation etc?

Thanks
