Neutrik aftermarket cable for Rel Strata III


Any suggestions for a good cable for the Rel, from amps to sub. Prefer something not expensive. Also, how would you describe the improvement created by the suggested cable.
System is Manley 300B Retro amps, ZU Druid speakers, Supratek Syrah pre.

Thanks for any suggestions.

synergistic research makes one...don't know the cost. i have a rel b3, if you do get an after market cord, let me know how it works.
I make very good REL aftermarket cable for affordable price-less than $100 for 8 ft link-please check my ad at A-gon 'REL'items.
I got a Cable Co. neutric/cable upgrade,for my Stentor.Driven by Rowland amp.This was 196 bucks,and made by XLO.Superb product,in performance upgrade and construction.
