interconnect cable 15' long

[Jaime]

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

cat-5 based is your best bet

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.
