I did a lot of experimentation and research many years ago with cables, making up my own, and today I still use home made cables for interconnect and LS.
The best sounding insulation is PTFE (teflon), as it sounds smooth and has excellent bass extension. The smoothness is down to its excellent RF characteristics; the bass is down to PTFE having the lowest surface energy of any known plastic - this gives it very low dielectric absorption, and this reduces low frequency errors.
I preferred OFC silver plated solid core copper. So for interconnects I buy 0.4mm PTFE solid core wire from Farnell; twist them with a drill into a single bundle of four conductors; then use four of these bundles and twist again. You then end up with a rope of 16 solid core PTFE wires - 8 for negative, 8 for positive. Incidentally, when forming the wire go backwards and forwards, so that direction is cancelled.
Next is the fun part. Pre-warm your oven to 200 deg C, and pop the twisted wire cable in the oven, leave for 15 minutes at 200 deg C, then turn the oven off, and let it cool overnight. This removes the work hardening in the copper, and as it is PTFE it can stand the temperature. The cable ends up having this new twisted shape as its natural state.
Next solder the cables to connectors, but you must use low melting point silver solder (LMP solder) again from Farnell. Some applications I add a screen.
For loudspeaker cables, do the above, but use 0.6 mm solid core wire.
I have not heard better than the above, but then I have not heard every cable out there.
So getting back to your question, if you don't want to make your own, then I would not spend more than 10% on cables. But what do I know? I make my own!

Great info Rob thanks! Will you ever sell your own made speaker cables anytime?
