FWIW I was recording at a studio back in the 80's that had all the new gear.....224X, PCM70, Yammie Rev1, etc.
They also had a EMT 140 but because it was "just a plate" they didn't really pimp it that much.
One night we were doing rough mixes and I had gone in the back to take a dfegad
and noticed the Plate in a back room.
I came back into the CR, and said "hey man, what's with that plate verb in the back?", at the time we figured digital = better but then the engineer patched the 140 in (API console) and we went "WOW, that thing sounds F'ing GREAT"
I've got the UAD-1 140 and while I don't think it sounds exactly like a real EMT 140, it sounds a lot more like the real thing than any "digital plate reverb algo" I have ever heard.
Try a Hammond patch (or the real thing) through the UAD-1 Plate 140 some time, that makes that sound
