At US$189, this Sony TA-AX500 is a strong deal, landing just above the 25th percentile of US$168 and well below the median of US$189 from recent comparable listings. In the current used market, finding this 1983 vintage integrated amplifier at or under the median price is rare, as other listings often climb toward US$257 or higher, with some asking well over US$350 for units with uncertain operation.
This model is well-regarded for its 80 watts per channel output and exceptionally low 0.05% total harmonic distortion, delivering clean, authoritative sound that rivals more expensive classics. The frequency response spans from 5 Hz to 100 kHz, ensuring full fidelity across the audio spectrum. At this price, it’s a genuine buying opportunity for enthusiasts seeking a reliable, high-performance vintage amp without the usual premium markup.

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.
