Where can I get _ultra_ high quality twisted-pair RJ11-RJ11 cables from?
Suitable for connecting an ADSL-specific faceplate-style microfilter's RJ11 port to an ADSL modem.

This is to protect ultra low signal voltages from a very long, high attenuation line from mains cables that are touching, or trying to touch, the DSL signal cables.
