A great recommendation... who is currently the chf. audio engineer at Capitol Studios, hired to redesign Studio A before the big Sir Paul McCartney LIVE gig a couple years ago. He's also the BEST for dealing with power/grounding issues throught your facility.

DO NOT PASS HIM UP for POWER/GROUNDING situations... even if you don't hire him for acoustic design.
Worthwhile info just to call him!!
