The brand of tape stock is surely irrelevant here - if the duplication equipment was correctly adjusted (and all too often it wasn't), the replay machine should have been presented with a tape modulated at the correct level and accurate decoding should have ensued. The adoption of 120uS for commercially duplicated chrome stock was intended to reduce HF crushing and thus improve Dolby tracking. Sadly, the consistency and ultimate quality of high speed duplicated cassettes seldom exceeded the mediocre.
