At USD 35, this is a genuine bargain: it sits well below the comparable-listing 25th percentile of USD 63, against a median of USD 115. The price is especially attractive if the amplifier and transceiver are both present and working.
The TA-SA200WR is a purpose-built S-AIR wireless surround amplifier, delivering useful power for compatible Sony home-theater systems and avoiding a speaker cable run to the rear channels. It is compatible only with specific S-AIR-equipped Sony receivers, so confirm your main unit is supported and that the EZW-RT10A pairs successfully. For the money, a tested example is an easy buy; just remember this is a system-specific accessory rather than a general-purpose stereo amplifier.
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.
