bmed,
for quite some time, I've had most of my gear on the side of the room with a 3M IC running from pre to amp which sits between the speakers on a low stand. I thought it might improve imaging, but I'm unsure if I can tell a difference; however, it definitely is less distracting--less of a reminder that I'm listening to gear rather than music. The lighting on my equipment is minimal, but still it's slightly distracting and I prefer to not look at it.
As to remote volume, I now find it indispensable since upgrading my system: I think there's a RIGHT volume where things sound best (not just louder or softer, but tonally right). Since that volume can really only be determined while sitting in the listening position, a remote volume control is almost necessary. I recently switched back temporarily to one of my former preamps without remote volume and missed my remote.
BTW, the designer of my preamp makes a big deal over how he has implemented a remote volume that doesn't degrade the sonics and that feature adds $500 to the retail price. If I had bought my preamp new, I probably would have foregone the remote just to save $$$;since it was second hand, the remote was included in the reasonable price and I'm glad it was.
