Gershman Avant Garde Upgrade?

I’m also a proud owner of a set of Avant Gardes which were upgraded a few months ago.
The Avant Gardes sounded wonderful before but, I must say, I’m ecstatic and extremely happy with the upgrade, well worth it !!!
The bass extends way lower and very well defined, the imaging is even more three dimensional and very precise. There is also a big improvement in the mids which appear to be richer, clearer and more pronounced.
Very happy with it.
Hope it helps

I am also looking for the upgrade version.  Love the AG already... Igoler, done your upgrade yet and any comment to share. 

I have not, yet:(

As a fellow Gershman owner...
 - just curious as to what amps you are dirving them with?

Thanks
