So - the laminate Eco Series models are good, very good in fact; but there is no doubt that this model is just a little bit nicer, with the addition of a solid Mahogany top. Mahogany is just the smoothest and most luscious sounding of woods, and the way that Kiwaya build their instruments (just like the old Martins, which are their inspiration) gets the absolute best out of it. That is to say, light and stiff, which means a resonant and vibrant soprano.
The longer neck on this one does make it sound half way between a concert and a soprano. There is certainly less of the very top end of the frequency response, and a little more beefiness to the lower register as well. Those extra frets can really be used as well - this has class leading intonation (although never perfect, it is certainly one of the best!) so you can strum and pick with great results all the way up.
So as a set up from the basic models, this little long neck makes itself a very worthwhile consideration.
