10 meters of interconect cable is too long.

A 30 foot speaker cable is much better than a 30 foot interconnect...........

It depends on many things. And over the years there have been a number of threads here in which the question of long speaker cables/short interconnects vs. short speaker cables/long interconnects has been discussed, with my perception being that a clear majority favors short speaker cables/long interconnects in most circumstances. In fact one of the advantages of monoblock amplifiers is often considered to be that they make it possible to have very short speaker cables.

Some of those dependencies: Preamp output impedance (the higher this is the more important it becomes to keep interconnects short, everything else being equal); speaker impedance (the lower this is the more important it becomes to keep speaker cables short, everything else being equal); balanced vs. unbalanced interconnects (balanced interconnects tend to handle long runs better); preamp compliance with balanced standard AES48 (which minimizes the importance of interconnect length); the internal grounding configurations of the preamp and amp (which affects susceptibility to ground loop issues, which is also affected by the resistance of the shield or other return conductor in interconnect cables, and resistance is proportional to length for a given cable type); and of course the characteristics of the specific make and model of the cables.

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.
