10 meters of interconect cable is too long.

I think before I spent all that money for something I did not know for sure would work I would order something like this, from Monoprice or online.  You can buy two 35 foot RCA's for a total of about $30 plus shipping.  I don't know whether these being coaxial are ok for your application but the idea is try some cheaper cable first to see if it works at all.  Be careful if you go this route, some cables come as a pair of RCAs that are both in one sleeve.

@kd8606,
I am using a pair of 25ft RCA’s between my preamp and amps (SET) with no sound degradation. Use quality audio cables and you will be fine. 

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.

I am running 6 meters you must go balanced for best sound at this length.Enjoy!!
