Oops, I see that in my earlier comments I referred to the "Rogue 88" when I meant to say "Rogue 99".
If you'd like a recommendation for an amp that's very open sounding and has a lot of pop, the InnerSound ESL amp works great with dynamic speakers as well as ESLs. I'm using them on my B&Ws and the sound is excellent at all volume levels. The ESL amp seems to provide more transient snap than other decent amps I've used without being harsh and it has excellent high frequency reproduction.
