All new room and modified system to fit the room. Converted the garage to a dedicated music room with remote AC system, completely dedicated 10 foot ground spike and dedicated circuits. GIK treatments throughout (diffusion on the ceilings and absorption everywhere else) has made the system sing.
And thank you to the following Audiogon gurus: SKushino, Syntax and Halcro.
Hi Jeff I have found the Avantgarde speakers continue to get noticeably better for at least 6 months of playing music, they do sound very good from new but you can hear improvements from playing music through the speakers over time clearly.
