The Canare I recommended above is a very high quality cable and if bought from BlueJeans Cable comes expectedly terminated. A balanced system is not nearly as finicky with cable choices as a non balanced one. IMO the Canare has no "tonal" trait, its neutral.
I do not buy into the "Cable Craze", I however believe in solidly engineered and manufactured cables and probably much more important connectors and terminations.
For a economy RCA cable I recommend and use, albeit I do not have much unbalanced equipment, the BlueJeans LC1
https://www.bluejeanscable.com/store/audio/index.htmFor an example I have a client in Los Angeles area with a very nice high end system whom had terrible a hum situation, he used high $ cables from a well known manufacture. Installation of the LC1 through out in his system completely cured this with much improved sound as a result.
Good Listening
