Marco,
Thanks for the invite. Doubt I'll be on the west coast anytime soon, but one never knows. I still have yet hear Avantgarde's out of sheer curiosity. Everytime I visit family in Atlanta, I call the dealer there and he doesn't have them setup yet. That's been going on for over eight months.
Right now I'm running my Theta Miles directly into a Pass Aleph 30. It sounds nice, but I feel I would be foolish to not sample what tubes have to offer, especially with the horns.
I will be sure to share my listening impressions. Thanks again for the great information!
Austin
