Quite extensive blurb on caps.
Not a lot of audio (-phile) details though....

In the progress of making a mic preamp to sound as transparant as possible for testing purposes..
You might reconise a 400B channel strip ;-)
Not happy. Old carbon pot distortions? Hmmm...

Switched to some 40 years newer desk with 'britishEQ' and 'midas preamps' (prfffff)
Replacing all sorts of caps with branded ones (like silmic, fine gold, FM, wima etc) give big improvements but also totally different distortion patterns.
Very difficult to get a musical (neutral?) balance, but hopefully in the end something more exiting then the out of the box MI thingie.

For those trying equal things: forget opamp switching, focus on caps and specially those in critical places like feedback loops (gain circuit, tone controle)

Momentarily designing a club system (playing Deadmau5 for hours on an end ;)
Low end of the fill in/out/underbalcony cabinet design boils down too 2 different 12' frames, very similar in magnitude response, but totally different representation of the emotional content of this program material.

So I did a (open air) distortion measurement of the raw speakers. (No cabinet)
Look at the differences in 2nd and 3th harmonic at around 600hz.
Blue being the coated speaker.
Higher harmonics show a similar difference albeit switched: non-coated being the 'better' speaker.

Now which speaker did I prefer with this (electronic) music ??
