RCA vs Phono cable


I have a 30+ year old Pioneer PL-560 turntable in perfect working condition (Shure M97XE cartridge/stylus) My Primare preamp has no TT connections so I just bought the Graham Slee Gram Amp2 SE phono stage with a PSU1 (should arrive Thursday). I will need a pair of interconnects to connect the phono stage to the preamp so I bought a used pair of Synergistic Research Level 1 UEF Atmosphere (RCA) 5ft/1.5m Interconnect cables. Then I saw info on "phono cables." Is there a difference? If yes, what? Should I have bought a phono cable instead of an RCA or a shorter RCA ?

Connect your phono stage to the preamp with whatever regular interconnect you have on hand. The Synergistic Research Level 1UEF Atmosphere (RCA) 5ft/1.5m Interconnect cables cables should work well.
@mewsickbuff  - If you are talking about the cable between your phono pre-amp and your pre-amp input, it is not really a phono cable. It's just like any other line-level connection. Use whatever interconnects you want. The one you purchased should be just fine.
The ZU Mission phono cable I bought is outstanding .
And better than the Mission IC I was using .
@schubert Zu Audio Mission Phono - this is what i use, bought them in rca to rca configuration with ground wire, but replaced connectors to DIN on one side. Great tonearm (phono) cable for MM/MC cartridges.

I also use Mission  Phono mk2 with WBT RCA’s, but this one is much more expensive.
Thanks all, glad to hear the Synergistic Research cable will probably do well. Got the Graham Slee phono preamp this morning and hooked it up with an ancient Red/Black RCA cable and it sounds pretty good. Noticing a lot less snap, crackle and pop and better soundstage than I've ever heard with my vinyl before. Bass is solid and deep. Instructions say the Slee will be operating at its best in about a week. Hope to hear a bit more midrange. Since the Synergistic Research RCA cable is "used" hopefully there'll be little need (if any) for break in.

Another question, my Husband has about a dozen 78 rpm vinyls that were his grandmothers. If I purchased a 3 speed turntable would he need to change cartridges to listen to 78's versus 45's and 33's?
