At £37, this is a strong bargain versus the current used market: it sits well below the £60 25th percentile and far under the £82 median, so it reads as an easy yes if it’s working properly. That kind of pricing leaves room for a service, a couple of missing cables, or just a little risk on an older amp and still keeps it attractive.
The A-404R is a solid older integrated with the kind of straightforward, listenable presentation many enthusiasts still like for everyday systems. It’s best when the basics are clean: quiet channels, intact controls, and no relay or scratchy-pot issues. If the listing is complete and unmolested, this is the sort of budget amp that can be a very satisfying buy rather than just a cheap one.

Pioneer traces its roots to 1937 in Tokyo, Japan, when founder Nozomu Matsumoto, inspired by the thrill of imported hi-fi speakers, developed the A-8 dynamic speaker and launched a radio and speaker repair shop. The business formalized as Fukuin Shokai Denki Seisakusho in 1938, evolving into Pioneer Corporation and embodying Matsumoto's philosophy of "Move the Heart and Touch the Soul" through audio innovation.
The brand excels across diverse hi-fi categories, pioneering Japan's first headphones in 1960 with the SE-1 and the world's first component-based stereo system in 1965 via the PSC-5A. Pioneer's portfolio spans amplifiers, speakers, turntables, and DACs, alongside landmark car audio advancements like the 1975 Supertuner-equipped stereo and the 1986 in-car CD player, blending home and automotive excellence.
Today, Pioneer holds a commanding mid-to-high-tier position in the market, revered for reliable, performance-driven gear that balances premium quality with accessibility. Its vintage components attract collectors, while current offerings appeal to discerning buyers seeking robust, innovative sound reproduction without boutique excess.
