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.

I think The Cable Company can special order you one made by XLO. What is not expensive? The XLO cable will be +/- $200
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.
