Speaker Cables For $300

Totally. I honestly know nothing about cables. 

Just my experience: every cable at Morrow Audio is custom made/made to order, the technician pretty much emails you about the progress when he is working on it, it's as devoted and small business as it gets. There is also lifetime warranty on the cable, you can get a replacement, fix, etc. for the cable you already purchased.   

these are still here:

Another vote for Satori. Also, another choice you may be able to find an original Audience AU24 used. 

May I suggest you check out Pinetree Audio  I bought a pair of their 8 foot speaker wires and I'm very impressed with the performance and there look! You will be pleasantly surprised by the price and they are made in the US

12AWG Oxygen Free Copper Wire

Nakamichi Banana Connectors

Satori. Over your budget a hair, but if you are patient, you can get close.
