Over 100', I would be surprised if a direct feed from a turntable would be usable with a moving magnet cartridge and with moving coil, it's unlikely that you would hear the music at all.
When I was a kid, with understanding of how to run wire but no understanding of the SYSTEM we're talking about here, I found that ten feet of wire extension created an audible loss of highs and injection of hum.
Over a short distance, lowZ is less of a concern, but it's still necessary to pay attention to cable routing to prevent noise intrusion.
Wire up a turntable the way it's made to be wired up.
The cartridge output level and impedance, cable impedance (length is a factor), signal level, equalization requirement, phono preamp input impedance, the EQ curve of the phono preamp, and turntable chassis grounding all make up a SYSTEM to deliver high fidelity audio. That's the way to wire it, period.
You'll find people in forums saying they extended the wires and everything was just fine. I'd like to know where they buy test records (they don't mention any tests at all) that allow them to make measurements of the system performance with and without the extensions. "Yup, sounds good to me" is probably the test.
