I have three turntables in two systems. One of the turntables is off the main gear table in one of the systems and requires a 20' stereo phono cable from the step-up transformer to the phono preamp. Zu Mission cable proved up to the task. It's quiet and the xformer output has no trouble driving the length resulting in uncompromised, full-bodied sound.
*This would not work if the cartridge had to drive its signal through that length of cable* alone, but if you use a MC with a xformer, Zu Mission will likely suffice at 24', however you terminate it. So I suggest a normal length tonearm cable to SUT, then 20 - 24' from SUT to your electronics. If you're using a HOMC or MM cart and expect to drive 24' directly from the cartridge motor, don't.
