TDK SA-X90 Hight Resolution Cassette Type II

TDK SA-X
The Professional Reference for the most discriminating audiophiles. Dual layered Super Avilyn formulation for well balanced performance throughout the entire frequency range. TDK has added a new dimension to high bias. TDK SA-X. In one leap, it goes beyond any other high bias cassette. Further than the reference standard, TDK SA. Far enough to come close to metal sound. It‘s all made possible by TDK’s technological breakthrough, an incredibly thin dual layer of Super Avilyn, each having different magnetic properties. SA-X has high frequency sensitivity 1.5 dB higher than SA. A maximum output level 1 dB higher throughout the frequency range. And the Laboratory Standard Mechanism, which lowers distortion to a minimum. Together they make SA-X the cassette that redefines high bias.
First appearance in 1979.
Last edition in 1997.
