The Logos fills my expectations for a superb center and has yet
to need repair of any type. The dispersion of the Quests fills
my need for high quality but not bright rears.

Hey Mitchell,

Beautiful system and welcome aboard. Let me know if you ever want to sell your Lightstar... :D

Hi Mitch,
Did you try driving the panels with the lightstar ? Is it better suited to drive just the woofers? I am planning on getting a lightstar 2 to drive my Aerius... bad idea?
I am a bay area local too by the way: if you are ever selling any of your stuff, would love to talk!
