searching/researching power amps and have found some very cool looking older amps....say 70's or even late 80's vintage. The style is unique and those analog meters are way too cool.

But i wonder how they compare against today's crop of amps.

I mean...80's sports cars cannot compete with today's sports car, but i view amps as different animals altogether. Assuming most of the technology was there back in the day.

Another question, if a 70 or 80's amp is rated at 100 wpc, does that equal today's 100wpc? Same for THD?

Thanks in advance!
