Hey Mike,
I used to own the Eros II and there is a really easy way to get the type of sound you seek. You use either a great solid-state preamp or no preamp (I used the Parasound P/LD 2000, a John Curl design with great success). Then you need to use a good hybrid (tube/MOSFET) amp to drive the ESL panels (the Monarchy Audio SE-160 monoblocks are magic with the Eros). This is my tested and proven recipe for getting the best out of these great speakers without spending megabucks. I'm sure you'll be very surprised at the level of performance you can attain with this setup.
No tube preamp I tried (including the Rogues and other more expensive units) could even come close to delivering the kind of bass extension and articulation that you can achieve with the above mentioned configuration.
