Tested and working is the key condition note here, and at US$90 this is a strong deal rather than merely fair. It sits well below the US$115 comparable-listing median and comfortably below the US$66 25th-percentile threshold—close enough to bargain territory that the missing remote is easily reflected in the price.
The HA-57 is a nicely capable vintage integrated amplifier: a robust, smooth-sounding Japanese unit with respectable power for everyday speakers and straightforward system integration. Working confirmation matters more than cosmetic perfection on an amplifier of this age. Before buying, verify both channels, all inputs, volume and balance controls, and listen for hum or scratchiness; if those checks pass, US$90 leaves plenty of value even without the original remote.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Hitachi is a Japanese electronics giant founded in 1910 by engineer Namiya Iwafune, who began the company as a small workshop producing electric motors. Over the decades, Hitachi grew into a diversified conglomerate whose industrial and component expertise laid the groundwork for its later entry into consumer audio and video. By the 1970s, the company had established itself as a serious player in the home electronics market, leveraging its engineering heritage to build a reputation for robust, well‑engineered products.
In the hi‑fi and AV space, Hitachi is best known for integrated amplifiers, power amplifiers, cassette decks, and later CD players and DVD‑based equipment. The brand also produced televisions, VHS and DVD camcorders, and a small range of portable audio devices such as MP3 players. Its audio components often carried the “Lo‑D” designation, signalling low‑distortion circuitry and a focus on clean, transparent sound. Hitachi’s speakers from the 1970s and 1980s, in particular, are still praised by enthusiasts for their balanced, engaging presentation.
Today, Hitachi is regarded less as a dedicated high‑end marque and more as a respected mid‑tier brand with a strong vintage following. Its classic separates and cassette decks are sought after by collectors and second‑hand buyers who value their build quality and straightforward, musical performance. While Hitachi no longer dominates the hi‑fi mainstream, its legacy remains visible in the continued interest in its older components and in the broader influence of Japanese engineering on modern audio design.
