Although the technique of double tape speed was not pursued further in the late phase of the tape decks due to the ever better technology and the ultimately excellent tape material, there were tangible advantages beyond the slight tonal improvement. At twice the belt speed (9.5 cm / s), the magnetized area is also twice as large as at conventional speed (4.75 cm / s). This achieves a significantly longer recording lifetime and better height stability. The problem of the intrinsic magnetization of wound strip material is much less noticeable. An advantage that should not be underestimated for high-quality archiving.
Of course, the halved playing time at 9.5 cm / s was problematic. So a C60 only managed to get to 2x 15 minutes, while the C120 was not recommended due to the poorer quality and low tape thickness.

With the C3, a/d/s - Braun also launched a tape deck at the beginning of the 80's, which was able to offer 2 tape speeds. Only a manageable number of top devices brought this function with them, which achieved a significant quality gain in terms of height controllability / external voltage distance and frequency response at the time of introduction. At that time, the C3 was competing with top devices such as the Nakamichi Dragon, whose excellent acoustic values it came close to.
