I am also looking for the upgrade version. Love the AG already... Igoler, done your upgrade yet and any comment to share.
Gershman Avant Garde Upgrade?
I'm the proud owner (purchased here) of a pair of Gershman Acoustic AG's that I love. I just spoke with Ofra Gershman who mentioned that they have an upgrade option for the AG's that if I understood correctly, redirects the bass making it less muddy, in addition to full replacements for the drivers, woofers and tweeters. Has anyone done this upgrade for the AG's and if so, what is your impression of the change in sound?
