Hithub CassetteRevive — Metal Type Premium Cassette Limited Edition

The Hithub CassetteRevive Metal Type Premium Cassette Limited Edition represents the pinnacle of magnetic tape audio performance in the compact cassette format, using pure iron metal particle tape with a coercivity of 1,500 oersteds and a squareness ratio of 0.87, magnetic properties that enable a maximum output level 6 dB higher than Type chromium dioxide cassette and extend the usable frequency response to 18 kHz at standard 4.76 centimeters per second tape speed — approaching the performance envelope of professional open-reel tape at 9.5 centimeters per second. Metal particle tape formulation requires a specialized metal-bias erase oscillator at 105 kilohertz in compatible tape decks to overcome the higher coercivity and achieve full tape erasure between recording cycles. The cassette shell for this limited edition is machined from a billet of matte-anodized 6061-T6 aluminum alloy rather than conventional injection-molded polystyrene, providing a resonance-damping mass of 34 grams compared to the 8-gram polymer shell, and a shell rigidity measurable as a flexural stiffness of 4,200 Newton-meters squared, thirty times the stiffness of standard polystyrene cassette shells, which eliminates shell-resonance coloration in high-fidelity playback systems. Limited to 500 individually numbered copies worldwide. Packaged in a rigid cardboard box with a 12-page booklet on 170 gsm matte paper.
