Best deal on unterminated bulk silver speaker cable for budget audiophiles

The SC-5 ePlus Cryo Treated Speaker Cable from Audio Art Cable would be the one you want 8ft for $950.00 plus what ever type of connector for an extra $50.00 to $100.00 dollars.

Another reasonably priced source for silver plated copper strand cables is to google “amplifier surgery”.  Located just south of Chicago.  He hand builds his cables and gets good reviews.  He is on e-bay and on etsy.  I have a pair and they are built well and sound excellent to my ear. 

I’ve spoken to this guy: https://www.ebay.co.uk/itm/372560920752 and he’s going to make me a pair of 2m, 8 strand solid silver core cables, terminated with silver spades and built in jumpers for a little over £400.
Cables are assessed for directionality and cryo’d. He’ll also sell them unterminated. He also does interconnects.

I don't know if he ships to the US, but I don't see why he wouldn't, he was very accommodating when I spoke with him.

Prior to that I was looking at https://www.monsterslayer.com/Metals/FineSilver.aspx.
They’ll sell you any length of solid silver core cable at various gauges. You’ll need to coat it yourself though, which is where I gave up.
