Speaking as one who has never seen, heard, or even smelled an ME amp
perhaps 
you can clear something up for me. As I understand it the ME is made up of

several modules in the signal path. Each of these modules has it's own 
feedback loop. Assuming that the module and it's feedback path are
correctly 
designed and thus pass an undistorted signal to the next downstream
module, 
why does this require such tight tolerancing in the output stage? I do 
assume that the ouput stage module has it's own feedback loop and is being

fed an undistorted signal. After all, even with global feedback, I know of

no design that takes the feedback loop back to the input of the pre-amp so

it is not entirely global even in that case.
