You may not like the sound, but I find the idea is interesting. Anyway, the sound on videos, especially on Youtube, depends on the recording materiel. The whole set is rather expensive (1850,00 €, 2106 $ at today's rate), so you'd better try them "in real life" before ordering...
I ordered some hardware to the man, and he's very kind.
