I have a pair of Model 2s that came with the interfaces but I modified them to work with a pair of the Acoustat servo amps I picked up. I also modified the panels to achieve greater dispersion. The sound fine on their own, but subs do improve things. I biamp crossed over at 100 Hz for low pass and high pass using 4 woofers.
I also have Quad ESL 57s and Roger Modjeski's ESLs with his direct drive amp. I can say the Acoustats hold their own against both of these speakers. As for more modern ESLs, the best I have heard is Sanders Sound which has an integrated bass driver. You don't get the dispersion of a SoundLab, but I could never see what the big deal was about SoundLabs anyway. Nice speakers, but I'll stick with what I have.
@ct0517 interesting you cross the Quads over at 60 Hz. I cross mine over at 100 Hz to avoid the intentional bump a 90 Hz that Walker designed into the speaker.
