[sdiy] vco's

[Scott]

Is there really much difference in sound between different VCO's?  
cgs vs motm vs ray Wilson vs Oakley, etc etc. (assuming they all have the same inputs, and same output wave forms, and not counting special VCO like quadrature, etc)  
I read a lot of stuff where people LOVE the sound of such and such VCO..  But, isn't a 10v p to p saw wave (or whatever wave) the same regardless of which VCO its coming out of?
