Interconnect Length

If I were to connect a turntable to my integrated, what would be the maximum interconnect length I could use?
Would 20ft be ok?
What kind of cart. are you going to try to use? With a MM cart. the capacitance of 20' will probably kill you. With a MC I'm guessing that only a balanced connection has a chance of working out.
Are you connecting the phono cartridge directly to the phono stage of the pre-amp, or are you connecting to the output of a seperate phone stage?

If the former I agree with the comment about 3ft. If the latter you could stretch it out a bit, but still wouldn't strech it out to 20ft. I keep all of my IC's no longer than 10 ft and use 3 ft when possible.
