Key Features
Kenwood didn’t hold back with the KX-620. This mid-tier workhorse packs a 3-head design, Dolby B and C noise reduction, and full manual tape calibration—rare at this price point. Tweak bias and frequency response to taste, ride the levels with precision peak meters, and command the transport with soft-touch elegance. Metal tape compatibility means it’s ready for high-speed formulations, making this deck a serious contender for audiophiles who demanded more than plug-and-play.
Historical Significance
Launched between 1982 and 1984, the KX-620 came out at the height of the cassette's golden age, when home taping was popular enough to be a hobby of its own. It sat in Kenwood's respected lineup and brought separate record and playback heads, a pro-grade feature, to consumers without the pro-grade price tag. It wasn't the flagship.
Sound Signature
When dialed in, the KX-620 sounds clean and neutral. Wow and flutter are low, and frequency response is tight and accurate. There's no artificial warmth or hype. With proper calibration, the deck records tape's character without adding its own, which makes it useful for duplication, archiving, or critical listening.
Maintenance
These decks were built to last, but time takes its toll. Belts dry and snap, idler tires harden and slip, and decades of use leave switches and potentiometers oxidized and scratchy. Capacitors degrade, head alignment drifts, and playback heads wear, especially if the deck saw heavy use or ran worn tapes. A full service means replacement belts, cleaning the capstan and pinch roller, demagnetizing the heads, and recalibrating bias and azimuth. Done right, a restored KX-620 can perform like new for another 40 years.
