No question, Delancey, you have excellent ancillary gear to compliment the Duo's. I heard the AG's with the Audiopax amps, and I happen to prefer the 6C33C tube of your Lamm's more than I do the KT88, particularly for the types of music that are accentuated by the virtues of the AG's. I've no experience with the Lamm/AG combination, but I would venture a guess that such a set up, along with your EMM Labs front end, could start a small pilgrimage from these boards to your home. Please post your impressions, whichever direction you end up going.

Howard
