Actually, with respect to bass, I would say the MC3+USB sounds more like AIR than USB.  So I would say Womaz should stick with his laptop via USB (the don't fix what isn't broken approach), or maybe look for a second-hand microRendu, sMS-200 or similar to try, and see if the 'end point' approach works in his system.
