I use Nakamichi 682ZX almost daily. Everything was recorded on Maxell Metal Vertex cassette, the best there is. Sounds excellent, though it can’t match my Nottingham turntable. It is not supposed to. And I use Purist Audio Neptune cables with it.
I send my deck to Willy every three years or so for a regular service. The deck has over 10000 hours on it but the playback head is in great condition. I do keep it very clean and use LAST head preservative regularly, usually every one/two plays. It takes a few seconds to apply and seems to work great.
