I've looked at the Model 1 a few times. It's nice, but not what I'm hoping for, and I confess the price on 4-6 channel DJ mixers baffle me (the Model 1 costs $4400 in Canada, that's more expensive than the 8-channel SSL X-Desk).
It both has way more stuff and not enough utility for me. I need more channels (at least 6 mono and 2 stereo), aux sends (at least 2, I don't even need returns, as I route back to the stereo channels anyway), 1/4" inputs (ideally xlr combo jacks), and that's it. No filters, EQs, saturation stages, or anything related to DJs (mix cues, rca jacks, phono preamps, x-faders). I'm resigned to that never being made, so I make do with what's available.
I do find it strange that mixer form factors tend to be segregated to specific use cases. So many mixers on the market, new ones added all the time, so little experimentation.
