I have a REL sub, model S-812, and use the high-level connectivity, coming from my amp. I got the Audioquest Rocket 88 REL specific cable in place of the supplied REL high-level connection (much nicer cable). I still don't understand that the phono stage would connect directly to the sub. Yes, the REL also has low-level inputs (RCA connections) but why would you connect the phono stage there? What am I missing?
