Cable with Neutrik Speakon connector


I recently acquired a REL Strata iii.  It is awesome with my Acoustic Zen Adagios.  However, I would like to find an upgraded cable with the Neutrik Speakon connector.  Any suggestions where I can find one?  Thanks.

I have tried the Signal cable with ny Strata iii. There was a great improvement over the stock REL cable. I since have upgraded to the Synergistic Research cable, better than the Signal. But for the money the Signal is very good. And Frank in a true gentleman to work with.
If you have a cable you like, this is a very easy DIY project. I bought my REL sub used and the seller neglected to include the cable. Piece of cake to build one.
I had a Signal Cable one but it came apart; I now use 2 made by an Audiogon member who use to advertise on here; they are considerably better. I will try to find his name.
Neutrik Speakon plugs are very cool...been using them on pro gear for years. I did find an angled Speakon plug that is great for my REL (less stress on everything) and I had fun making the cables...much less expensive that way...shrink wrap tubes galore, and, weirdly, the plugs are made in Liechtenstein!
I have a Nordost Baseline made to Rel spec. Huge improvement over the stock cable. If memory serves me there was a $35 upcharge to make it to Rel spec a couple of years ago.
