Kimber 4tc good enough?

Mr. steve 59

Your Hegel H360 has a DF of >4000! for 7ft length, you need 16 times (in parallel) #0 AWG cable. Not very likely you do it. but you may...
Any way rather than look for some branded #12 AWG or less thick cable, do yourself a favor and gear up to the thicker you can get. For 4x 0 AWG, you may use a connecting bloc and at the end, a short #8 AWG that would fit most banana plugs or spades.
By ignoring this, you will use only a small friction of your Amp’s capabilities to drive a speaker at perfection. So do the math, a #12 AWG cable is about to use only 1/288 or 0.34% of what you invested in your gear!

That's umm, how do you find the math for that? I will start with a heavy guage for the bass and keep the 4tc for top octaves bi wiring.

One option is to run 8TC for the bass and 4TC for the midrange/tweeter. Bass drivers (woofers) are current-hungry and the larger gauge 8TC works better.

These Kimber SCs exhibit high or very high capacitance, which cannot be recommended.

Try Canare 4S11 single, not bi-wire and get a ft. or two extra and make your own jumpers. Use to own 4 and 8TC and I find it’s a little grainy and forward sounding. You’ll find the Canare is more relaxed or natural with a better stage. Canare takes a lot of hours to burn in so give it time. Can be purchased off Amazon among many places and it’s very affordable. Search here and other places to learn more. It’s a great cable and I feel walks all over the Kimber. You’ll have to spend a lot more to do better.
