Compared with the obvious alternative at US$760—a more ordinary used preamp from the middle of the market—this looks like a strong deal. Your anchor set puts the 25th percentile at US$760, with a median of US$1,170 and a 75th percentile of US$1,650, so this listing is sitting right at the low end of the current used band, not above it.
That makes it the kind of buy that rewards a careful, enthusiast-grade system match: this era of Sony ES preamps is well liked for a clean, composed presentation, solid build, and genuinely serious analog switching and phono-stage credentials for the money. At this price, the upside is straightforward—if it’s complete and functions properly, you’re getting a respected high-end vintage control center for entry-level money. Only the usual age checks matter here: noisy switches, tired electrolytics, and missing remote or accessories if they matter to you.

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.
