The EMT 927 is very similar to other professional 16" broadcast turntables- large platter, large powerful motor, large bearing, idler drive.
The hype around the 927 is the typical hype around EMT. I own an EMT 950 BBC Widebody, by the way, along with most of the other decks discussed in this thread.
The people jumping onto the 927 bandwagon have no experience with the big Fairchilds, Gates, Rek O Kut's, Commonwealth and other more obscure 16" broadcast tables, and so their enthusiasm may be excused, but there is nothing very mysterious about the performance of these decks compared to belt drive.
The downside of the EMT 927 is pretty steep, though. The price is ridiculous, but worse, you have to use the poor EMT 997 arm, or the earlier Ortofon. Because the arm must be mounted to the chassis of the 997, your flexibility is gone. And, as another poster has said, you just spent the equivalent of a nice new family car on something that really just earns you bragging rights on forums like this one.
The EMT phonostage is not a contender, either.
