Has anyone had any experiences with an HAA certified installer? Good?...bad? I ran into this website: http://www.homeacoustics.net and was very interested in learning more about audio calibrations. I'm having my Mitsu calibrated by an ISF certified tech (still kinda skeptical, but willing to try things) --- just wondering if I would benefit from an HAA installer to calibrate the audio side. Should I be skeptical of this group too? Just wondering. Thanks!
