Inexpensive speaker cables

Blue Jeans Cables, great stuff!

I'm probably opening a can of worms but I still want to bring up the obvious. The most effective speaker cable is the one that can transmit the current from Amp to speaker with minimum loss. i.e fattest gauge you can buy (many scientific experiments available online e.g. http://thewirecutter.com/reviews/the-best-speaker-cable/). So why not Monoprice Nimbus 12AWG 4-conductor for bi-wiring

I have 12AWG Taralabs 4-wire sitting in a drawer. Didn't notice any difference when I had to replace them with the Monoprice 12AWG 4-wire due to my need for longer run.

I really enjoy my Signal Cables.  High quality and reasonable price

the funny thing is you have this fancy fat wire going from the amp to the binding post and this really skinny wire going from the binding post to the speaker or crossover. 

I've tried a number of cables over the years, all with their own unique sonic-signature.  I try to steer-clear of cables with higher capacitance in general  as they seem to roll-off the treble.  That said, I have to agree with gdnrbob and nonoise regarding ZU cables.  I'm using the Event-1's and they have been the best IMHO than the rest I've tried.  Triode Wire Labs also are really good cables.  Both of these though are over your price-range but both will give you a trial period and no worries on returns...  Good Luck !
