I use a pair of tricked out Dynaco MKIII monoblocks and modded up PAS to dive the Druids. Beats the big modern ss and SET amps I've used for dynamic presence and bringing the music to life. The power can bring down the house, but the textures at low listening can charm the night away. (The SET was smooth and nice in that studied listening way, but as a musician myself, not my cup of tea.)
