The manufacturer of the headset advised this was not preferable due to the potential for ground loops on the mic side.  Has anyone had any experience with ground loops on the mic from headsets connected to the rear jacks?  I'd love to use them to free up the front of the rig.

This manufacturer is badly mistaken. There is no technical basis to his 
advice. Many of us have used boom mic headsets like the Yamaha with the 
rear panel connectors for years.
