I'm looking for a pair of interconnects that won't shatter the bank....


....but I have some extenuating circumstances that may make that impossible. First things first, the interconnects both have to end in RCA Male-to-Male because I don't have an XLR option and every component uses RCA connections.

I am running a bi-wired and bi-amped system so the interconnect runs are rather long. The longest run is around 9 feet and connects my preamp to my Subwoofer In ( the Subwoofer is a Sunfire SDS-12 ). The second run is shorter but still long. It's the Subwoofer Out to the Amplifier In which is about 6 feet. Obviously, I am looking for interconnects that already have those RCA connections attached.

Any ( nice, polite and helpful ) suggestions?

There are some amazingly good cables available on Amazon for a fraction of the advertised brands.  Like 10% of their cost. Next rung up I'd have to go with Pangaea. I got a a set of their TT cables and am very pleased for under $100.  Beyond that, your wallet is the limit.
Check out Kimber Kable. They have silver which has the lowest resistance. You don't need silver for the subs, but I REALLY like silver over copper for everything else. Amp, preamp, DAC, phono and not that much $$.
What I’d do is get myself some decent looking but not too much costing cables from no matter what brand or store. There are many myths about audio cables and most of it is marketing babble to lure your into paying top dollar for ’left rotating silver atoms’ that in the end are just metal strands worth only a couple.

Of course if it makes you feel good when you pay a lot for some nice looking audio equipment then that can be worth the investment, but only for that reason, that it feels nice, while probably it doesn’t really sound better. With a blind A/B test most people won’t be able to hear a difference. You only hear a difference because you just shelled out $500 or more for some esoteric interconnects and now your brain tells you you want/need to hear a difference.

And read this article and maybe Google some more on audio cable myths:

Any cable from the various UK manufacturers such as Chord, Atlas, ecosse, QED....these brands are seldom mentioned. They all make excellent lower budget line cables.
