I run my EB1's with a Marantz PM7001 (70w) amp. For my level of listening, which I admit is hardly Monsters of Rock levels, I find that the dial is usually at quarter to most of the time, if everyones out then it can go up to ten-to, but no more. When I had a had a Uniti (50w) that was usually set at between 40/45 (out of 100), more than enough.
I don't think I've ever had any combination that has needed me to put the amp past half way.
