I might be wrong but is 'HiFi' not invented as a marketing trick?


Was it? Can you give the evidence you have for that?

I have assumed that - in English - it meant 'High Fidelity'. With an
amplifier this means that for audio signals the output is an accurately
scaled version of the input. Hence the term 'amplifier'. :-)

I
recall a hip 1958 ad from Philips for that years new models table radios


Your evidence that Philips invented the term for this ad is?...

What's your standard of performance? Reading a 100Mhz scope? My standard
is about music with as little as possible interference, whatever
technology, cosmetics, cyphers, brand or anything.


Mine also. Hence the above definitions of 'High Fidelity' and 'amplifier'.

Slainte,
