I don't have any secret master tapes; in fact I haven't even got round to doing any recording yet. (I will however be recording some old reel to reel tapes on my Revox G36 later when I have time). I've just started relistening to our old back catalogue of pre-recorded cassettes that we bought all those years ago. I have just been stunned just how good the deck is. It costs but a fraction (less than 10%) of my vinyl front end.
Listening to the Dragon through the rest of my kit (Tron Meteor tube preamp, Quad IIs and Avantgarde Duos) has been a humbling experience. I never thought cassette could be this good - reel to reel yes, but cassette - surely not! We have all known how good a top vinyl front end can be, but how many of us truly believed in the old compact cassette?
