RDGRIMES: That's an excellent idea. Of course Velodyne (my sub) recommends first the RCA connector/cable/LFE input to any user who in fact has a SW/LFE output jack on his receiver or pre/pro, but speaker connections and a built-in varible (80hz to 120 hz)crossover (purely analog) are also provided (as they should be at the more than $1000 price of this Velodyne SPL subwoofer).
Going this route may provide another benefit: use of "Pure Direct Mode" on my Marantz 6003 receiver. Until now I've used the "Stereo" mode, as Pure Direct would also cut out the bass management.
My only question would be: what's the downside? Although having excellent 2-channel stereo is more important to me than the surround, nonetheless the surround and center channel are excellent for movies. Were I to run my left and right speaker wires directly to the subwoofer and the subwoofer speaker outs to the left and right monitors, would I be limiting myself in other ways?
Would I be correct in assuming that when I place the receiver in 2-channel stereo mode, the digital circuits are shut down, but they are active again when I switch to movie/surround mode. If so, then the Oppo-83SE would make sense, as 2-channel stereo would maintain an analog audio path.
Thanks again for your suggestion.
