Oh wow, what a deal, Ed!
It was between this and a Sony 3 head deck from CL.. All the reviews I found said go with the 4600, as it has absurdly good sound quality for a 2 head machine. I think I might be hanging on to this one for a while.
Additionally, Dolby didn't just toss out licenses for type S circuitry. A deck had to meet certain criteria to be able to wear the Type S logo.
