Down to earth inexpensive? Avalon's in general are so reveling of quality, beyond these I haven't a clue.

I don't have anywhere near the experience this reviewer has had with different amplifiers but his description of the character of these mono's is the truth.
A used Ayre V-1xe or the Atma-Sphere MA-1 or 2 all of which were suggested above. The Karma 150's are another option. You will absolutely regret replacing your Eidolons, don't do dat. While Eidolon's do present a difficult load for lesser amplifiers, don't get caught up in power ratings, it's not about watts it's about current and quality. Reread Johnsonwu's post and trust your own ears in your own room.
