In between -85 to -80DB I start getting a hum (from the woofers). It builds up almost like the cartridge is picking up the phonics. Its repeatable. I don't let it get to far in to the hum before I'm cranking back the volume to -80.
My speakers are not all that efficient (86) so listening at that level is not uncomfortable.
Is there a setting that I might need to consider changing (like low level filter) or something similar?
With the cartridge/arm off the record, I can turn up the volume to well over 0 with no noise at all.
Any suggestions most welcomed.

The subsonic filter is on by default for phono input if I remember correctly. If you are using a seperate preamp you would need to enable the subsonic filter in config for that input.
Either way it sounds like you have some sort of issue with the new cartridge, wiring or something that needs to be resolved.
