    8 conductor 14 gauge cable from Vafam Sound with an 8-pole Speakon at the speaker end and four dual banana plugs at the amplifiers. 15' long because apart from when I had a separate equipment closet I've never wanted my power amps any farther from the speakers.

That is a Marantz 7C and the box on top of the Orion cross-over switched between it (with adjacent CD players) for 2-channel and the Lexicon for home-theater.

I'd like to say that it was a little smoother. The noise floor was slightly higher but not audible at the listening position.

I later switched to using the Lexicon second zone (it's all analog) for 2-channel with sound being about the same but providing remote volume control with an attenuation display in dB.

System edited: As a consequence of moving, all the video and surround sound equipment is in storage.
