I use spades from my REL cable on the same 5 way posts that carry the banana plugs for the main speaker cables so they stay out of each other's way. The REL puts a very high impedance load (100,000 ohms?) on the amp output so it shouldn't burdon it in any meaningful way, and it works very well. Not sure if any other sub uses this method, but that's one of the things that attracted me to the REL sub.
Anyone attach an REL sub to Cary amp?
I like the way the REL subs connect into a system, with the signal being transmitted to the subwoofer via the speaker terminals on the amplifier rather than an output on the pre-amp. However, on most Cary tube amps there are only one pair of binding posts, or as in the case with my amp, a neutral and both an 8 and 4 ohm tap (I use the 4s). This would require having both the speaker cables and the sub cable connected to the same set of binding posts. They are multi-way binding posts that could easily accommodate the second set of wires for a sub, but I'm a little uneasy about doing it. Has anyone ever tried this with a Cary, or any other amp with a single set of posts for that matter?
