I also own Innersound Eros speakers, and use the ESL amplifier; I strongly agree that this amp is ideal for use with Eros or Isis speakers, or any other electrostats. The ESL amp just "locks on" and makes incredible music with them.I have also used the ESL amp with Acoustats, and it was better than anything I've found to drive them as well. As a bonus, the Innersound ESL amp is capable of high-current output, and works exceptionally well with speakers that need current to "open up" and sound their best. I have personally used it with Gallo Reference and Apogee Duetta Signatures (full range planar ribbons),with truly excellent results. You just can't lose with this amplifier, because it's compatable with a wide range of speakers and systems (RCA & XLR inputs, cool operating temp., compact size and 45 lb wt, 300 watts @8 ohms, 600 into 4, per channel, and stable into 1 ohm loads! Need more power? Buy 2 and biamp. Upcoming (full) review in TAS.
