I know about the "high end broker" and "A 10 audio" they both sell colibris new or second hand a bit of googling .
What the plastic concerns i dont know about all the colours it should not make any sound difference i would think and no i am no vd hul expert what i do know is that he lives in the dutch countryside and that he is very much devoted to audio so youre not buying a hyped marketing product but something beautifull made by hand , i would not take the high output ones personally but the low ones (lower moving mass. )
