This was my favorite amp for years with my Zu Druids. Smooth, quiet, and great tone. This one is a prototype but Peter assured me it's 100% equivalent to his original Patek, just with a different power supply case and wiring.
I used it occasionally with less efficient speakers and it never sounded strained. Hard to find a better 50 watts.
