I own a Model 1 also and freaking love it, but I just picked up a Condesa Lucia V and have to say, I'm totally converted. The isolators alone are worth the switch. I miss 6 channels on the Model 1 since I use a lot of Ableton drum fills and loops, but honestly probably going to sell my Model 1 compared to the Condesa. Pure tactile, expressive joy. Both are amazing but the knob action on the Condesa are so expressive. Just so much for to work it in the mix. Both are gems though. Enjoy!
With that said -- not going to lie, still remember the sets I've done on the Radius 4 or Rane's. The feeling creates a totally different experience and it changes the way you mix. Casual, fun - "closer" to the audience somehow.
