Kenwood KA-3020 (1993)

Name: Kenwood KA-3020
Brand: Kenwood

The Kenwood KA-3020 is a solid-state integrated amplifier released in Japan in 1993 at ¥35,000. According to Audio Database, this pre-main amplifier was highly evaluated in Europe, particularly the UK, before it was ever released in its home market. That is part of why it has a quiet following today.

It's a straightforward analogue design with a few thoughtful touches. Rated output is 50W + 50W into 6Ω and 45W + 45W into 8Ω, both at THD 0.05% (20 Hz-20 kHz). It draws 115W under the Japanese Electrical Appliance and Material Control Law, weighs 7.4 kg, and measures 440 × 138 × 349 mm. Kenwood centered the design on a pure signal ground line and a logical internal layout routed along the signal path, which made for a clean, quiet sounding amp. There's also a Source Direct switch that bypasses the balance and tone controls for the shortest possible signal path.

There was also a Special Edition variant, the KA-3020SE, which appeared in the UK market around the same period. Gramophone reviewed the SE and found it musical and enjoyable, though not completely transparent. It admitted the amp was "not overendowed with muscle," rated at a fairly modest 30 watts per channel. The SE differed from the base model in some details, and one Russian listing notes Elna capacitors inside the SE. The two models' specs are often conflated in listings, so exact figures vary by source.

Long-term owners report good things. One Fixya user said they'd had their KA-3020 for over 20 years and loved it, paired with Tannoy speakers. The known failure modes are typical of the era: dry solder joints causing intermittent channel dropout, and channel selectors that can wear or gum up. None of it is difficult for a competent tech to address.
