Have reactivated for nostalgic reasons my old tape deck. For that I have ordered a total of three 10-packs of the above cassettes. Of this I opened one and used 5 cassettes for testing purposes. After that I returned to rest again. I tested the tape on my Aiwa AD-WX 828 with auto rec Calibration System, an Onkyo TA-2830 with BIAS knob (for manual bias), and a Yamaha KX-W 321st The average maximum recording level in the peak is at all decks with Type II (chrome) tape at about +2 dB. (TDK, Fuji, Sony). This can usually make pretty good shots. Only times for clarification: I'm not here the Hi Freak with with special Einmessverfahren etc. works. However, the decks are all serviced properly and function properly. To make it short: The C 60 SHX chrome lose ALL after shooting up to 5 dB and sound after dull and partly distorted and indeed in all decks, no matter what the maximum recording level (+3 dB, +2 dB, +1 dB, 0dB , -1 dB, -2 dB) Also increased or decreased bias settings do not change anything. As mentioned earlier function other cassettes properly on the tape deck. Maybe I also just caught a 10-pack with any manufacturing defects, because see other reviews the SHX 60 yes quite positive. Too bad.
