No, but my E12 Mont Blanc is still kicking after 7 years. That and an X3ii was my original rig. I needed something that would drive full size cans on the road. It easily plays crazy loud without distortion. I think the gain switch is intentionally difficult to operate so you don’t accidentally deafen yourself.

It’s a beautiful workhorse milled from a block of aluminum, features Texas Instruments op amps, and an ALPS potentiometer with a satisfying feel. It’s a special bit of gear to me, and I don’t see myself ever parting with it.
