Hello Lewm and Geoch.
Yes, the Wilson Alexandria speakers do have an impedance dip that can be difficult to overcome at times. At one time, I did try the Lamm ML2.1 amplifiers and did not find them to be able to drive these speakers to my satisfaction; however, others have had satisfactory results with the Lamm ML2.1 speakers and the Alexandrias...please see Steve William's A'gon thread regarding his positive results with this combo in his fabulous room.
As Geoch mentioned, I am utilizing the Lamm ML 3 amplifiers. I am very pleased with how they synergistically work with these speakers; please refer to the 2011 CES reports regarding this combo ML3/Alexandria Series 2 speakers; my Alexandrias are series 1. Dealer disclosure for the Lamm Industries electronics.
Best,
Alan
