If you go to the Solitaires YouTube page you'll find no less than ten videos of the Scala that give a fair representation of what a Wersi OAS instrument sounds like. The videos can't show the dynamic range of the instrument which is quite amazing. Demo 7 has some nice examples of the articulation some of the instruments have. If you have time give all the demos a listen and you should be impressed. The capability of these instruments by far exceeds those of any big three offerings.
