Jas Audio GP 120 Integrated Amplifier (Solid State) Selling my fantastic integrated power amplifier. This is a very surprising and powerful amp. Uses high quality components like Elna, Nichicon, and Sanyo. Also has one of the most out here remotes I have seen in a faux timber. These had a RRP of $995 USD roughly $1500 today.

This listing is a significant outlier: at A$575, the Jas Audio GP 120 sits well above the 75th percentile (A$335) of recent AUD comparables, making it an ambitious price rather than a bargain. The median for this model is A$180, so you’re paying more than triple the typical used asking price for a solid-state integrated amp that originally retailed around A$1,400 (US$995) and is praised for strong build quality and sound that exceeded its entry-level cost.
The GP 120 is well-regarded for its clean, balanced performance and reliable solid-state design, offering real value when found near or below the median. At A$575 in very_good condition, it’s only worthwhile if it includes original accessories, shows no signs of capacitor aging or channel imbalance, and comes from a known original owner. Without those upsides, this price is hard to justify against the A$112–A$335 range where most buyers are finding the same amp.

Sanyo Electric Co., Ltd. traces its origins to 1947 in Osaka, Japan, when Toshio Iue, brother-in-law of Panasonic founder Kōnosuke Matsushita, launched the company using a disused Matsushita factory to produce bicycle generator lamps. Formally incorporated in 1950, the name "Sanyo"—meaning "three oceans"—reflected Iue's vision of global reach across the Pacific, Atlantic, and Indian oceans. From these humble beginnings, Sanyo rapidly expanded into consumer electronics, pioneering Japan's first plastic radio in 1952 and pulsator washing machine in 1954.
In audio and hi-fi, Sanyo earned recognition for mass-market components like stereo systems, introduced in 1958, and the groundbreaking all-transistor DC-600 system in 1963. The brand produced reliable radios, tape recorders, cassette decks—often rebadged for other labels—and hi-fi systems, alongside televisions and amplifiers. Later ventures included acquiring the U.S. Fisher brand in 1975, elevating its profile in receivers and speakers aimed at everyday enthusiasts.
Today, Sanyo holds vintage-collector status rather than an active hi-fi contender, its reputation rooted in affordable, innovative Japanese engineering from the 1960s-1980s golden era. Once a "3S" giant alongside Sony and Sharp, it catered to mid-tier buyers seeking solid performance without audiophile premiums, though its absorption into Panasonic in 2009 shifted focus away from dedicated audio gear. Collectors prize well-preserved Sanyo pieces for their durability and nostalgic appeal in retro setups.
