Cheapest but good cables….

Hard pressed to beat Mogami for cheapest and best.  Here on Audiogon is a small builder doing speaker cables and interconnects with Neutrik connectors.  I ran a pair of his balanced on a 30K pair of active speakers and they rocked.

Or you can order plain speaker wire non-terminated.  

Hey, for less than $3.00/ft. You cannot go wrong.  These run a pair of Mordaunt-Short 10 monitors.

Thanks for that Celtic!

I usually use Mogami too, but I lashed out on some of this:
 

Of course you need to dress the ends yourself… exactly the same as using Mogami.
I think that the Benchmark has SpeakOn connectors??
If so Neutrik SpeakOn is easy, and their stuff is nice to work with.

I am not sure that the cotton is better than Mogami, but it gives you some other option to consider.

I went for cotton as there is no teflon and a lower dielectric constant than the plastic insulation. So I considered it like a po-man’s battery biased AQ speaker cable… Just rather than a battery, I am using a dielectric with does not polarise.

Flat speaker cables? Nordost. 
Interconnects that you can hid under the rug? Balanced BlueJeans. I actually prefer them to Mogami as they’re slightly more laid back and are less harsh. Mogami Studio Gold XLRs were ok but not great in my system with benchmark dac3 hgc. 

Just buy the cheapest Morrow ICs that are long enough for your use. They lay flat and are transparent enough.
