I used to have the InnerSound Eros Mk-II. The best amps I found to drive them were the Monarchy Audio SE-160 tube/MOSFET monoblocks. They had a warm, musical character, with very lovely treble performance. They blended more seamlessly with the Eros than any other amps I tried.
The InnerSound ESL amp had plenty of power and pop, and the clarity was outstanding, yet it made for a thin and bright sound with the Eros. I would avoid it unless you'll have a lush-sounding tube preamp preceeding it. If you're not using a preamp and are using the InnerSound crossover/amp, then a tube/solid-state hybrid amp makes the most sense in my view (having tried a lot of different combinations myself).
Happy Listening!
