Ambitious. At US$2,399, this is well above the usual used range I’d expect for an Onkyo P-388f; comparable pre-owned sightings cluster far lower, with clean examples and even serviced units often landing around US$1,000 to US$1,400, while older forum chatter suggests they’ve historically changed hands for much less when not freshly restored.
That said, it’s a respected late-80s/90s high-end preamp with proper balanced outs, serious build, and the kind of refined, low-noise control section that still makes sense in a good system. If this one is truly mint, recently serviced, and complete with remote/manual/box, the premium is easier to understand—but at this ask, buyers should want documentation and confidence that the restoration and cosmetics are exceptional.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Onkyo traces its roots to postwar Japan, founded in 1946 in Osaka by Takeshi Goda, an engineer at Matsushita Electric who envisioned high-quality Japanese loudspeakers. Initially established as Osaka Denki Onkyo K.K., the company began production in 1948 with the acclaimed ED-100 speaker featuring a 25 cm driver, quickly building a reputation through LP concerts and innovative designs that resonated with audiophiles.
The brand excels in premium home audio, renowned for AV receivers, hi-fi amplifiers, and surround sound speakers that deliver exceptional clarity and power. Its portfolio spans turntables, DACs, headphones, and cables, bolstered by acquisitions like Pioneer's home electronics division in 2015, enabling cutting-edge integrations such as internet radio and high-resolution streaming.
Onkyo holds a solid mid-tier position in the hi-fi market, prized by discerning buyers for reliable performance and value rather than ultra-high-end exotica. Despite bankruptcy challenges in the late 2010s, its revival under new ownership preserves a legacy of technological innovation and pure sound enjoyment, appealing to both vintage enthusiasts and modern home cinema setups.
