Who makes budget speaker cables which are truly “good” or “exceptional” in quality?

I made myself a pair of cables using DH Labs Q-10 bulk wire and DH Lab's locking banana plugs (nice quality). They aren't dirt cheap, but a pair of 8ft cables is under $400 with DH Lab's 10% coupon. These were a big improvement over the Audioquest and Nordost cables I was using. The Q-10 cables won't be a match for every system, but in my system (Parasound JC-5 and Goldenear Tritons) they provide a nice smooth sound with excellent bass and great imaging. A step up in clarity compared to the Audioquests (Mammoth) and a much fuller, richer sound than the Nordost (Red Dawn). 

Anyone else tried Knukonceptz Karma 8 guage with their bananas, they sound great to me and very low cost for what you get. Their interconnects also work very well.

Clear Day, Blue Jeans, my Analysis Plus Solo Crystal Oval 8’s at the used price that I paid...

very happy with Blue Jean Cables - even made in US - Seattle - I have a pair of their RCA interconnects and locking banana plug speaker cables - I save a ton of $ on the latter by terminating them myself. Great banana plugs and online instructions.
