I have owned 40.2 and anniversary 30.2. I believe the 40.2 was the best full range monitor I have ever owned. Alan Shaw always liked to claim Harbeth to be amplifier agnostic, and I believe to a degree he is correct. They seem to keep the Harbeth signature with a wide variety of amps and despite lowish sensitivity even the 30.2 can sound suprisingly good with lower power.
I had too may amps on the 40.2 to remember, both tube and SS. my favorite though was an Audia Flight SS. The 40.2 seemed to respond well to quality power. I have a pair of Vinnie Rossie VR120's for sale currently. I did not own the 40.2 when I started experimenting with Vinnie's gear but I know he had a show stopper set-up 4-5 years ago with 40.2's paired to a single VR120. I always wanted to hear my 120's paired with 40.2s but I listen in a space much too small for them now, got kicked out of the big rooms by wife and kids LOL. The 40.2 or its successor will be a speaker I return to someday, probably in retirement when I get my room back :)
