40.2s need POWER! I use them with with Simaudio 400M at my large place but the new Hegel H590 and Gryphon Diablo 300 will be very good choice. I would stay away from Pass Labs for Harbeths - both companies have rather warm sound signature that can just be too much.
The amplification for 40.2s does not need to cost a fortune to perform very well.
