hi I have had for 4 years now a PM 25 which works well and I love, I lack some new features like optical output etc, I know there are much newer amps (mine is from 1985-1990 approx).
those are the specs from a new one
Mesures
Réponse en fréquence (entrée analogique) : 10 Hz à 40 kHz
Rapport signal/bruit (audio) : 90 dB
Distorsion Harmonique Totale THD (audio) : 0,1 %
and these from mine

Specifications​

Power output: 30 watts per channel into 8Ω (stereo)
Frequency response: 10Hz to 50kHz
Total harmonic distortion: 0.1%
Signal to noise ratio: 83dB (MM), 86dB (line)
so in paper it seems worse lol
as far as sound quality as it evolved?
thx

Why do you want to upgrade? What could another amplifier do to make you happier? More power, better sound? Soundwise amps do not differ that much.

What room and speakers do you have? In the room you can make the biggest upgrade, as in treating the walls for less echo.

A well designed modern amplifier won't sound worse than this. Also, there's nothing to suggest the PM 25 is a "classic" amplifier that sets it apart from anything else in that era. So, if you are happy with it, don't change it.

i thought the one i was comparing it would be worse because of its specs :
new one :
Frequency response: 10Hz to 50kHz
old one
Réponse en fréquence (entrée analogique) : 10 Hz à 40 kHz
even though i may not hear the difference

Those specifications are completely irrelevant! Any good amplifier should have a flat frequency response. What is more, you can't hear much above 16kHz let alone between 40 and 50kHz. I suspect any modern, well designed amplifier will sound as good if not better than the PM 25. But, if you like it, don't change it.
