Need speaker cable

How about 65 CENTS per foot? Why pay huge $$ for cables? You can buy 50 conductor flat grey cable, used in computer systems, for $65 for a 100 foot roll from surplus outlets. There is a certain well regarded company selling flat cable for big bucks. They use flat, multi conductor cables too; the first half of their wires for the + conductor and the other half for the - line. I suggest you use every other wire for + and the interleaving wires for the - side. It is a tedious job, stripping 200 wires (pulled apart for 3 or so inches and stripped 1/2 inch or so) to make a pair of cables for a stereo system (it takes me about two hours - I do it while watching PBS documentaries), but it's really worth the bother. The wire "breaks in" in about two hours and you should listen carefully during that  time. The sound changes radically. You may think you wired the strands together incorrectly, initially. Do check very carefully when you connect the strands together (every other one, got it?). Check it with a meter of some kind. I've never heard a better cable. Be sure to cut the cable at right angles to the length so that all the conductors are the same length. Yes,they will be really ugly cables. But they do go under carpets easily.

I haven’t listened/tested high end cables but I am very skeptical of spending $500 on cables for a $1000 amp. (I think I googled the OP’s amp correctly)

I’d suggest spending money on other parts of the setup.  

superultramega,

If you haven't tried it, you have no useful opinion. $500.00 spent on cables for a $1000.00 amplifier is by no means extravagant.

I am still trying to get my head around 65cents per foot ‘Ugly’ cable suggestion by boomerbillone 😇
