NB - the 215 is the best deck I've heard. I got one out of a duping house. It didn't record well, but it played like new.

Sony produced cassette decks equipped with Dolby B,C and S.
I have measured the record-reproduce SNR on a Studer 8 track machine equipped with Dolby SR at nearly 96dB linear, not weighted! It was too close to the noise measuring gear limit!
Yes Revox B215 is a superb cassette deck as it's professional brother Studer A721, equipped with transformer balanced Ins/Outs and parallel RC. But both they have a little flaw: While they are 3 headed decks, the R/P head block is constructed in such a way not permitting azimuth adjustment of the record head! You had to live with the manufacturer's set-up. If you were lucky your head block would be close to "a few" degrees of azimuth error between the record and reproduction heads.
