Is there a noticeable difference between CCA and pure copper conductors for stereo RCA cables? Not asking about speaker wires, just RCA.

Oh those Copper Plated Aluminum wires in cables with the 'RCA' brand.  For short interconnects probably not much difference. But for long interconnects (maybe 3 meters) 25 feet for sure, they are a poor choice.  That aluminum foil shield/return with it's very high end to end resistance may have 25 dB poorer background noise than really good interconnect (think BlueJeans LC-1).

I'm looking at the Mediabridge Stereo RCA  cables on Amazon. I currently own a 4ft BJC LC1 and it damn good but I need a minimum 8ft cable right now and the Mediabridge is much cheaper. I contacted them and they said the cable uses a CCA conductor. How about using two Mediabridge subwoofer cables? Those have a lot of sheilding but still CCA.
