Default interconnect cable 15' long

I want the power amps near the loudspeakers.

The distance between the amp and the preamplifier is more that 15 feets.

You can suggest a good cheap DIY interconnect cable for this situation? I will need an input transformer in the power amp?

Best regards Jaime

is 15 feet long enough to start worrying about capacitance and resistance? the IC's aren't balanced are they?

I've used cat-5 before for longish cable runs..

Ground all the extra wires!..You might only use 2 pairs (left and right + and - ) and then have 2 pairs left over-ground them!
It will help kill some of the noise..
I've also put a ferrite cores (from old monitors,etc) at each end of the cable,to help keep RF/noise out aswell.

I once had a homebrew cat-5 cable that was about 35 feet long,and there was very little noise/hum with the two tricks mentioned above.
