The timing is neutral here: this is an older generation piece, so the main question is whether you want the sound and build of that era rather than chasing newer features. At kr 2,000, it sits right at the 75th percentile of your recent comps and above the median of kr 1,431, so this is ambitious rather than a bargain.
That said, the model has a solid reputation as a straightforward, musical integrated amp with enough grip and drive to make sensible speakers sing. If it is genuinely clean, fully working, and original, the upside is getting a well-liked late-analogue-style amp without paying collector money. I’d want confirmation of noise-free controls, stable channel balance, and that no service issues are hiding behind the price.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Proton Electronic Industrial Co., Ltd. emerged from Taiwan in 1981, establishing its base in Banciao, Taipei-Hsien, as a manufacturer targeting the U.S. consumer audio market with high-quality components. Linked to Fulet Electrical, which produced notable NAD amplifiers, the brand launched around 1984 to expand into consumer electronics, including acclaimed TV monitors like the 600M and 602M models. By 2009, it remained active, building on a heritage of precision engineering from shared facilities with brands like NAD and Dynaco.
The company focused on premium hi-fi gear optimized for real-world performance, emphasizing tuners, receivers, amplifiers, and integrated systems that drove everyday loudspeakers with exceptional clarity. While not delving into headphones or cables, Proton's lineup prioritized robust playback under practical listening conditions, from radio reception to vinyl and cassette sources, earning praise for its engineering rigor in the 1980s.
Proton holds a solid reputation in vintage hi-fi circles as a mid-tier powerhouse, favored by collectors for its reliable, high-value sound that punched above its price point. Positioned as an accessible alternative to elite brands, it appeals to discerning buyers seeking durable, no-nonsense performers rather than boutique exotica, with ongoing interest in its schematics and restored units.
