RCA Interconnect recommendations

When you do you blind listening, can I suggest you just write down whether you think the sound is better, worse, or the same.  Your cable switcher should remove the cable, then randomly insert one or the other test cables.  Sometimes you will be comparing a cable with itself - that's illuminating.

You can get random numbers from tables, or pseudo-random numbers from Excel.

If you repeatedly play the same record, expect it to deteriorate through wear!

I think this is a worthwhile test. While I've tried some of the Beldens, I've never tried and tested this particular set of BJ ICs. I've thought about buying a pair of these as a test set, loaner set, and to use for other components to plug in and leaving my main cables alone. Imo Its really good to have a nice baseline value set of cables like this in any case to test and compare other cables too fwiw. Be sure to give them 10-14  to just uncoil, relax the cable internal dielectric inside, let them play for two weeks before making an early judgment imo. Yes, even your ears and mind will adjust to them but I think its fair to give them a little time to relax and settle in without touching them.  Best of Luck, good move to test these first. You might end up liking them.    

I just went through similar experiences. Picked up WBC (World’s Best Cable) from Amazon. Got a pair of the directional Mogami with Amphenol connectors. Really happy with them. Just ordered a couple more pairs. Not very expensive vs Red Rivers.

 I have an inventory of Darwins (very bright) and a pair of Van den Hul (nice, but very expensive). 

I'm using Graham Slee CuSat50 cables between my sacd player and preamp. Also between my phono preamp and preamp. For around $200 per pair, I think they are excellent. The only seller that I find is on eBay. They ship from the UK.
