Whoever claimed Linn Kans were transparent?

Transparent has a pretty well established meaning in audio which is a component/process that adds nothing measurable to the signal. So no speaker - not even a Linn Kan - can be transparent.

You will see people using it in other contexts i.e 'transparent sounding' when what they actually mean is 'doesn't sound all horrid and distorted' or 'I can hear what the vocalist is singing' but this isn't transparancy it just means the system being described is not total crap.
