Oh man, now why'd you have to go and post that link? Who can look at that Marantz receiver and not be depressed at what our gear looks like today???
The best feedback was when you would turn the knob and it had that nice oily smooth feel with the little clunk. So much better than the click you get nowadays. Then again the big tuning knob, the mass that would let you really feel you were doing something, and if you got it going fast would keep spinning so that with a little practice you could give it a swipe and across the dial it goes gliding smoothly to right where you want it.
The knob or the dial, which provided the better feedback? I don't know. Both were great.
