i had an interesting discussion with my dad the other day. according to him, older amps ( 80s, early 90s) have looser bass.
this got me wondering, how much have amplifiers improved over years? can one hear an audible difference between a 1980s amp and a brand new amp today? ( in terms of sound quality, soundstage, etc)
does it mean an old amp is definately inferior to a new one?

thanks!!
