Some years ago I compaired the innersound eros mark 1 speakers with the then top of the line ML Requests (same room and electronics) and the innersound electrostats were much cleaner, faster and had much better bass. Since then, both innersound and ML have made improvements. While ML has a wider sound stage, I don't move around when I'm doing serious listening so innersound would be my preference. However, I do like some of the ML offerings especially the older CLS speakers and the SL3. The innersound electrostats were the only speakers (along with sound labs) that I've heard in a realistic price range that could compete with my now defunct modded Dayton Wright electrostats.
