RCA Interconnect recommendations

Good suggestions above - personally I use Zavfino Fusion interconnects (DAC and PS) which I think are hard to beat for the price, but I love my Acoustic Zen Hologram II speaker cables, so at some point I may try the AZ interconnects, but I dont feel like I’m missing much.

Contact thecableco.com and take advantage of their cable lending library. Free and they can advise you on a couple different cables to try. If you can ask for John Pharo, he’s a great guy to work with.

but I can tell you I am using Cardas Golden Reference (no longer made) with my Rega/Lyra Kleos/lLinn Linto. And they have some trade ins for sale as well.

The https://www.thecableco.com/ recommendation is probably your best place to start.  I have not tried their program, but I have looked at the site many times and have been impressed with the choices and prices.  I may dip my toes into some higher priced cables in the future.

Currently I have a mix of Cardas Clear, WBC, and https://sites.google.com/view/pine-tree-audio/home. Pine Tree just received a best of reward. I have found their cables to be comparable to Cardas Clear for significantly less money. 

Of all the cables that don't make an objective difference, interconnects are those but what absolutely does make a difference is expectation bias. 

"Of all the cables that don't make an objective difference, interconnects are those but what absolutely does make a difference is expectation bias."

On this, I have to disagree.  I'm not a cable snob and definitely believe that the law of diminishing returns kicks in pretty quickly.  But comparing three interconnects that I happen to have on hand (Cardas Ultralink 5C's, AudioQuest Red River and Graham Slee CuSat50), there are very obvious differences in them.  The AudioQuest is too bright and definitely fatiguing.  The Cardas is not as transparent.  Right now, the Slees clearly sound best.
