Not convinced by that...
The best 1/4" replay, IME, was always the Studer A80..
Best portable recorder the Nagra 4S, with the Nagra T being the best dubbing/timecode machine - though it's replay wasn't up with the Revox PR99.
The Telefunkens always had a "vintage" sound nearer to that of the aged Ferrographs we had when I first trained...
