This is the standard stereo Compact Cassette we are all used to. That is mentioned because this title is on Elcaset, and DCC, it will be on 8-Track as well as DAT tape cassettes. With so many cassettes, we are trying to be quite clear what one you have selected. If you do however misplace an order for the wrong format, that will not be an issue, we will gladly exchange it for you. This Cassette is a type II Cobalt tape Hybrid, that is very unique, it has a special 3M cobalt formulation in a special tape shell with a precision bridge for high quality sound, mastered directly to compensate for the limitations of the Cassette compared to the 24bit original recording. It features Dolby S noise reduction. The unique part about this tape is how it was mastered… it will play and sound amazing on any standard cassette deck, with any setting. But… if you want the absolute studio quality result, playback on a Dolby S system with the automatic METAL detection set. The system will detect this is a Metal tape cartridge, and adjust accordingly. Since the Cobalt tape we have selected performs well above the chrome tape usually used in Metal tape, we chose to use this and it functions amazingly well across universal platforms. So rest assured this cassette not only will last, but it will sound amazing on any tape deck, and even better on a high end audiophile deck that features auto selection tape detection and Dolby S noise reduction.
