Kenwood KX-600 (1980-1982)

Name: Kenwood kx-600
Brand: Kenwood

That rare deck that makes cassettes feel like an event — solid as a tank, smooth as silk, and loud in its analog conviction.

Overview

If you’ve ever dropped a blank tape into a deck and felt like you were about to commit something important to analog history, the Kenwood KX-600 knows that feeling. Built between 1980 and 1982, this Japanese-engineered stereo cassette deck wasn’t trying to be flashy or futuristic — it was built to record and play back music with unshakable reliability and a sound that owners still describe as “FUN!” in all-caps, decades later. It arrived when cassette fidelity was hitting its stride, and Kenwood wasn’t messing around: the KX-600 is all metal, all business, with a massive aluminum front panel, chiseled handles, and a fully mechanical presence that makes modern gear feel like plastic toys. It was originally priced at 550 DM, which put it in the serious-hobbyist tier — not entry-level, not flagship, but the kind of machine you bought because you cared about how your tapes sounded and how long they’d last. And last they did: one seller noted their unit “has reached our days in excellent condition,” and others call it “very rare in these days,” which says something about both its build quality and how few survived with care.

This is a 2-head, single compact cassette deck with a Sendust record/playback head and a ferrite erase head — a solid, proven configuration for the era. It supports all four tape types: Type I (Normal), FeCr, CrO2, and Metal, with manual selection so you’re not guessing what your tape needs. The motor is an electronically controlled DC type, which helps keep wow and flutter down to a stellar 0.05%, and it uses a single capstan for stable tape speed at the standard 4.76 cm/s. The whole mechanism is described as “solidly assembled,” and the cassette receiver design avoids cantilever issues with rigid fixation — meaning your tape sits flat, stays put, and doesn’t wobble its way through playback. It’s not a 3-head deck, so you can’t monitor while recording, but what it lacks in pro features it makes up for in consistency and durability.

Owners rave about the experience: “The mechanics work clearly, smoothly and gently,” one noted, and that tactile precision carries through to the controls. The KX-600 uses what Kenwood called “Soft Quasi-Touch Control,” which isn’t full touch-sensitive tech like later decks, but a refined mechanical system with soft-action buttons that don’t clack or stick. The front panel has those charming “big-eyed” arrow indicators with warm, pleasant illumination — not too bright, not too dim — and the analog VU meters are part of the charm. Inputs include line (77.5mV) and mic (0.2mV), with a line output of 0.39V, plus “Finger” jacks for headphones and dual microphones (L/R), making it surprisingly flexible for home recording. It even has independent switches for Dolby NR, REC MUTE, and TIMER STAND BY — thoughtful touches that suggest Kenwood expected people to actually use this, not just stack it under a receiver.

And use it they did. The KX-600 exceeds DIN 45500 standards when paired with high-grade tapes like TDK-SA, Maxell UD, or Scotch-Metafine — the audiophile cassettes of their day. Its frequency response stretches from 30Hz to 16kHz on Metal tape, with a signal-to-noise ratio of 64dB using Dolby B, and total harmonic distortion held to 1.3%. It’s not quite CD-level, but for 1980, it’s impressively flat and clean, especially in the midrange where vocals and instruments live. One owner put it simply: “The deck sounds like a GOOD VINYL!” That’s high praise, and it speaks to a sound signature that’s warm but not muddy, detailed but not clinical. It’s also, as one enthusiast emphasized, “100% ANALOGUE! That says it all!” — a declaration of purity in an era just beginning to flirt with digital.

Key Features

Fully Metal Chassis & Rigid Cassette Handling

The KX-600 doesn’t just look like it means business — it’s built like a piece of industrial equipment. The entire casing is metal, including the front panel, buttons, and knobs, and it weighs in at 5.9kg, which tells you everything about its heft and vibration resistance. The cassette receiver uses a rigid fixation system that eliminates cantilever design, ensuring the tape is held flat and stable during playback and recording. No wobble, no tilt, no misalignment — just consistent contact between tape and head. That’s a big reason why owners report such smooth mechanical operation, even in units that have been refurbished decades later.

Manual Tape Selection & Analog Precision

While some decks auto-sensed tape type, the KX-600 gives you manual control over four tape types: Normal, Fe-Cr, CrO2, and Metal. This isn’t a limitation — it’s a feature for those who know their tapes and want precise bias and equalization settings. Combined with the analog VU meters and “big-eyed” illuminated arrow indicators, the whole interface feels deliberate and tactile. You’re not guessing what’s happening — you’re seeing it, hearing it, and feeling it through the soft-touch controls.

Connectivity & Control Layout

Kenwood included a thoughtful array of connections: RCA (tulip) jacks for line input/output, a DIN socket for additional linking, “Finger” jacks for headphones and dual microphones, and independent switches for Dolby NR, REC MUTE, and TIMER STAND BY. This level of control suggests the KX-600 was aimed at users who recorded live music, made mixtapes, or even dabbled in home broadcasting. The stationary switching design keeps cables secure, and the 220V power supply indicates it was primarily built for European and Asian markets.

Collectibility & Value

The Kenwood KX-600 trades in a wide price range today, reflecting condition, location, and whether it’s been serviced. Recent listings show units selling for as low as $60 and as high as $229, with European markets showing €40 (Kleinanzeigen) to €85 (Bazos Slovakia). In Poland, one sold for PLN 650, in Argentina for ARS 190,000, and in Czechia for CZK 12,000 — the latter possibly as part of a full system. These discrepancies reflect local demand and the fact that fully functional, cleaned units command a premium. One listing noted the unit had been “completely cleaned and refurbished,” with lights checked and replaced and the tape head cleaned — exactly the kind of service needed after 40+ years. Belts, idler tires, and capstan motors can degrade, and potentiometers may oxidize, but the solid build means most issues are repairable. Service manuals are available for the KX-500, KX-600, and KX-800, making restoration feasible. Given owner reports of reliability and superb sound, and descriptions calling it “very rare in these days,” the KX-600 is a sleeper hit among cassette collectors — not a superstar like a Nakamichi, but a deeply satisfying workhorse that delivers way beyond its price tag.
