Kenwood KA-6004

Kenwood KA-6005 – Integrated Stereo Amplifier

The Kenwood KA-6005 is a classic integrated stereo amplifier produced in the mid-1970s. It was positioned as a higher range  model in Kenwood’s lineup and features solid build quality, a brushed aluminum front panel, and excellent analog sound. With a dual power supply, discrete components, and a strong phono stage, it delivers warm, detailed sound suitable for a wide range of speakers.

This is an excellent solid-state amplifier from Kenwood (also branded as Trio in some markets), known for its smooth and pleasant tonal character with sufficient power output for most home setups. It includes a generous number of input options for connecting external devices. A key advantage is the presence of two phono inputs with built-in preamps, allowing the connection of two turntables simultaneously — no need to swap cables, just flip the input selector.

Today, the KA-6005 is sought after by vintage audio enthusiasts for its musicality, reliability, and timeless design.
