Can electron tubes or analog tape fit something big to something small?


Possibly so.


Transistors, discrete circuits with few components with little or no negative feedback are in too.


What may be wrong with negative feedback?
It makes abrupt the translation from linear to overload so that something big cannot fit to something small. The distortion would be nasty. It is also transient intermodulation distortion [Otala].


Mr Black's genius invented negative feedback on a ferry trip and wrote it down on a small packet. Clearly an invention that made much of what we see today possible but possibly not an invention made for top quality audio.


What is meant by big?
The live music signal itself.


What is meant by small?


A small mobile phone, a small size downloaded file, a small IC etc.
