It is a large room for sure (I'd be so lucky) It is 25-30 ft from the amps, to the preamp ect, and the amps are how close to the speakers? HOW BIG IS THAT ROOM??? LOL I'm sure you have it all figured out, BUT does it really have to be so far anyway, ANY way to get it closer? I'm guessing it's a target for guest, kids. You want to open up the room? I mean why do you REALLY need to move it that far. Gotta clear the floor for salsa dancing, or prayer meetings, partner, OCD kickin' in, WHY you gotta move it? Ay? I'm an ol' mechanic, I TRY to stay out of trouble, NOT get out of trouble. I hate moving cables period, everything sound whacky until they (the cables) or I settle in. I haven't figured that part out yet.
