At one point a friend of mine bought a very old amplifier from the 1960s and invited me over to try it out. Before listening we opened it up and saw it was running on BJTs, standard for the time period.
So, we hooked it up to a pair of KEF R3s and started blasting after which a very strange but pleasing audio phenomenon happened. It was especially apparent on voices, a kind of echoing decay, it gave the sound a sense of spatiality and layering that is hard to describe, also made it much more interesting to listen to than his modern class AB amp. Although compared to the modern amp the sound was lacking in clarity and speed amongst other things.
I'm wondering what exactly in the amp circuit or the BJTs created this effect?
