Good to hear from Willy here. I play serviced by him 682zx almost every day. Thought about sending the deck to him this fall but put it on hold. I do it every three-five years. Maxell Metal Vertex tape gives absolutely best performance. If you never tried this tape with a calibrated higher end Nak, you don't know how a nak can sound. Don't waist your effort and money on 660 and 670 series let alone below. 680 series, ZX-7, ZX-9, 700ZX, 1000ZX. 682ZX and ZX-7 are best value.
