I don't think I could part with my DM12. Not yet, anyway. Nor the S8. I just enjoy playing them too much. Same with my Grandmother. I had a feeling that between the S8 and DM that there'd be some overlap with the Peak. I'm not sure that it brings enough of a difference to the table but I haven't played with the filter in person so it's hard to tell. But the input is much appreciated! I wish I lived near a synth dealer so I could try it for myself, I'm so curious about the Peak.
