Warnerwh,
I have also owned the Innersound ESL (driving the Eros, as a matter of fact). I think it's a very good amp, and - especially used - a fantastic value. What I never got from the ESL was the harmonic richness of tubes, something I value highly. A couple of reviews of the various Class D amps have suggested that that richness is characteristic to a degree. Here, I'm specifically thinking of Srajan Ebaen's review of the H2Os. Coming from a long time tube addict such as Srajan, I found his comments to be rather striking.
