Offered is „TA - N55ES“ by Sony as second-hand device from the category „Transistor-Poweramp“ on audio-markt.de - the online market place for high-end. The advert with the number 7200283110 ends on 20.12.2026 at 18:29 o'clock.
Compared with the usual modest integrated amplifier available at this money, the Sony TA-N55ES at €150 is a genuine bargain. That is well below the €241 25th-percentile figure from 33 comparable listings, against a €294 median and €329 75th percentile, so even allowing for its age, the asking price is unusually attractive.
This is a substantial ES-series power amp: 110 watts per channel into 8 ohms, with plenty of current, a sturdy build, and the useful option of 300-watt mono bridging. It suits listeners wanting controlled, confident drive rather than a lightweight budget amp, and its clean, understated presentation remains appealing. At this price, a properly working example is worth pursuing; simply confirm both channels operate cleanly, there is no hum or protection trouble, and the speaker terminals and relay behave normally.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sony emerged from the ruins of post-World War II Japan, founded on May 7, 1946, by Masaru Ibuka and Akio Morita as Tokyo Tsushin Kogyo K.K. in Tokyo's Nihonbashi district. Starting with radio repairs and Japan's first magnetic tape recorder, the duo secured transistor licensing from Bell Labs, pioneering the TR-55 transistor radio in 1955. Renamed Sony Corporation in 1958—from the Latin "sonus" for sound—the brand symbolized Japan's ascent from cheap imitations to innovative leadership, fueled by Ibuka's engineering prowess and Morita's global marketing vision.
Sony's hi-fi legacy spans headphones, amplifiers, speakers, turntables, and DACs, alongside landmark formats like the Compact Disc in 1982 and Blu-ray. Iconic products include the Walkman for portable audio revolution and Trinitron televisions, blending consumer accessibility with cutting-edge tech. Today, offerings like the Signature Series headphones and ES amplifiers target discerning listeners seeking refined soundstaging and dynamic range.
Positioned as a mid-to-high-end powerhouse, Sony commands respect among knowledgeable buyers for blending mass-market reliability with premium performance, outpacing many pure audiophile brands in innovation and value. Far from vintage relic or niche boutique, it dominates with forward-thinking engineering, holding strong market share in headphones and streaming ecosystems.
