The design and construction of M15A's mechanism is the most beautiful thing in the R2R's world. solid as a piece iron and it's smooth operation no other makes can compare, every friend of mine must say wow in the first sight when it run but we didn't say wow when it sang maybe impressed by the mechanism too much.
machine can't sang right a way by the time it arrived tips from Ki ( change tape to face out, replace in out put sockets etc,) but still one thing can't be done is CCIR/NAB switching and tune, I don't understand the Germany handbook and those marks on the amp broad, even the circuit drawing is not detail as the Studer's manual, so what I can do to listen it's sound is to play the Tape Project's tape without tune up. sound quality is so so to me no wow, edge of the image's body not sharp enough, not too clear with mud, less live emotion. I guess it is better to forget it's stock playback ( need to find out CCIR/NAB switching and tuning), it is very easy connect directly to the repro head to use a external playback pre amp should be better in result, Sorry to Telefunken's fans, it is my personal opinion
