I recently purchaed EPOS ELS3 and tried them in my main room home system and liked them a lot. Really nice. Then I plugged back in my Silverline Sonatina II's and the SS II's blew away the ELS-3's. The main difference was the body of the midrange and upper bass, which seemed to be MIA in the ELS3. OTOH the ELS3 had more air on top.
Bottom line to me was simply that the ELS3 is an extremely enjoyable speaker in its own right, and if you don't A/B it to a better speaker you might just be happy living with it. I think I would.
I bought the ElS3 for my home office, which is where they are now. Very nice fit.
