What Is The Cost Of Amplifier Casework?


What is the approximate cost of the casework on the big Krells, big Pass Labs and big Gryphon amps?  What is the approximate cost of  casework on similar big solid state amps?

I don't know, but I've heard rumors that along with heat sinks can add up to the single highest expense.
Once I read 30%, which could be true, but it would vary greatly based on how fancy it is. Jeff Rowland may be at the top, and Van Alstine at the bottom.
