recommendation for best low cost rca interconnect

I second the IC-3 from Audio Art. A young company that understands the price per performance ratio with high end audio in mind. These are excellent IC's. No, I have no affiliation with Audio Art I just own them and love them.

Signal cables w/bullet connects. Great value, great sound, beat the stuffing out of my (much more expensive) Taras.
And, as everyone says, Frank is a great person, and I'm all for giving my $ to a great person.

depending upon your taste, outlaw audio continuous cast copper cable at $55.00 is a good choice.

another to consider is the element interconnect, unshielded with bullet plugs.

since you didn't indicate your preferences i am indicating these cables based upon personal experience.

i own a pair of each.

i have personally auditioned many varities at different prices. if you want to ask more questions about cables, feel free to ask.

I'm surprised not to see the oval one ic by Anaylsis plus. This cable is under 100.00 and I find myself always coming back to it after changing cables. Currently between my Philips sacd and NAD intergrated.

Acoustic Zen WOW!! should be able to get a used pair for the money you're looking to spend.
