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

Anticables! Speaker, Interconnect, and Power cords

Check out their testimonials and reviews.  Paul Speltz does not advertise; depends on word of mouth.  I have used many very expensive cables in my system, but Anticables have, to my ears, easily bettered all of them.  You can buy a cable, put it in your system and if you don't like it, you can send it back for a full refund.

Some say these are simply magnet wires--totally untrue.  But again, very reasonable prices and a money back guarantee.  How can you lose??  Lots of good info on their website to ponder. 

Actually, male enhancement pills are not (rpt not) really a good example to make your point since male enhancement pills work. At least that’s what I’ve read.

Geoff, okay, that's all that matters. What you don't know won't hurt me.

A very well reviewed company is blue jeans cable - bluejeanscable.com well reviewed and budget enough for my use. Their web is simple to use and order from. I've been very happy with them.

I cut the ends off a set of cables to "upgrade" to WBT Next Gen Banana plugs (bad mistake).  Bryston, I believe, epoxies the banana plugs to ensure no vibrations enter the cavity where the conductor meets the plug.  Anyway, I found four 12AWG(measured) conductors are used.  Two are twisted for the  plus side and two to the negative side.  I am not sure who makes the cable for Bryston, but on one site, it was suggested Wireworld does the actual manufacturing.  For further info just call 1 800 632 8217 for a Bryston rep.
