This is a very interesting thread.

This is basically what started this thread. After having my new gear blown away so clearly by vintage this thread started on the why, not whether it was but simply to figure out why?
I would have bought a Marantz vintage pre and amp but you do not go and change parts in a valuable vintage piece. So I used pedestrian Fisher amps to test.
I have not heard a Marantz but have no doubt they sound fantastic. Look at the size of the coupling caps. Marantz 9

They are MUCH bigger than the ones Fisher used at the time the Vishay ERO caps. Marantz at least was aware of this affect even then. So was Fisher as the better models would have more bigger caps. (physical size)
When changing to the Jensen Copper Paper tube they were MUCH more dynamic (and wayyyy bigger) then the original. The VSF even better.
One thing of this thread was you just do not go throw in new coupling caps and be better than the original vintage ones easy. By the looks of the size of the Marantz coupling caps one better be ready to spend $$$ to replace them as with as good....
