RMGI SM 911 is the famously improved BASF tape which offers more headroom, plus a 3 db higher input/output and a smoother surface than older tapes. It has a coated back and the no-dropout-technology makes this the ultimate and most sold studio Master tape.
There is no reason for buying 30 year old NOS tapes – RMGI SM 911 tapes are more cost efficient and rank higher in overall quality.
