I have had a lot of synths come and go over the last few years. To buy new stuff, old stuff always has to go first. Regarding Roland boutiques I can only compare to what I have heard and spent time with but I used to own the Jupiter 8 and TB-03 Roland boutique devices. I sold both pretty quickly. The sound just does not compare in terms of quality to the cheap Behringer gear. I might pick up an SH-01 clone at some point. The Roland will not figure in my choice. It will be the Behringer or I may sell some eurorack pieces and get an Intellijel Atlantis.
