I was pondering this the other night and thought I'd bring it to the forum. I am a child of the '80s, and the only real speaker memories of the '80's and early '90's are of my dad's plain old JBL bookshelf speakers. Those speakers died and now he just has this thing. At the time I thought the JBL's were pretty nice sounding (I was, like, 10), but other than that I have no real frame of reference to compare today's speakers against. I haven't heard much vintage equipment, but I know some people prefer it. So - If you were to compare a current, well-regarded mid-level bookshelf (or tower or whatever) against a similar, well-regarded speaker at equivalent prices from 10, 20, 30 years ago, what differences would you likely hear? Would it be a drastic improvement, a difference in style alone, or would they actually be pretty close to the untrained ear? Just wondering the degree to which changes in technology translate to clear and obvious improvements in sound.
