I recently purchased used LG speakers, and also brought a used Adcom GFA-545 power amp to drive them. Now I am looking for the RCA cables to connect my Harman Kardon AVR525 receiver to the Adcom amp. My budget is about $50 or less (if possible), but I can also stretch my budget as much as $75 to $100 if the quality of cable is significant good. I am looking for your opinion, I hope will good suggestions from you.
