I have a Dominion X at home right now, it belongs to a student of mine who bought it as his first serious synth. I have played with it for a few hours and I must say that it's a lovely instrument. It sounds great, mfb filter and all, it feels good, it's small and lightweight, and very easy to program once you get to understand the quirks and shortcuts they made in order to save space (and parts, probably). It has a full, aggressive sound.
As soon as I feel to have spent enough time with this little beast, I'll write a review.
