Cmo, I've heard good thing about the Incognito rewires, but I'm pretty sure they terminate at the back of the tonearm, and then you need some kind of interconnect to get from there to the preamp. Here's a copy of an email I sent to someone who inquired:
Generally tonearm internal wiring is extremely fine single or stranded wire. (SME even uses a ribbon coated wire in their Model IV) The advantage of this ultrafine wire is that it doesn't cause resistance to the tonearm bearings.
Plus, the tonearm itself (usually) provides the necessary shielding. But it is very fragile. So much so that separate short connectors are often used to connect the cartridge to this internal wiring -- although some people prefer to solder cartridge clips directly to the end of this fragile wire.
Usually this fine wire is terminated either at the base (main post) of the tonearm with a five-pin DIN plug or a pair of RCA jacks. Sometime the wires just come out of the back of the arm in a big loop, and terminate under the turntable base with an RCA teminal block.
In any case, the run from this "termination point" to the phono preamp is usually accomplished by a pair of singled ended (RCA) or balanced (XLR) interconnects whose make up is specifically designed to carry the small voltages of phono cartridges, but which A.) are sturdy enough to sustain plugging and unplugging and general handling and B.) have an outer shield to protect the signal from hum and
Radio Frequency Interference (RFI)
That's why I was having trouble understanding Thomas' question.
