Unknown condition is the only real hesitation, but at A$130 this is a strong deal: it sits well below the A$204 25th-percentile comparable and less than half the A$278 median asking price. Even allowing for its age, that leaves useful room for a replacement cable, case, or battery service if needed.
The HP-P1 remains an appealing compact DAC/headphone amp for an iPod-based system, with a capable DAC, three gain settings, line input/output, optical digital out, and enough output for efficient headphones and most portable models. Its internal battery is the key check—roughly seven hours when healthy—and compatibility centres on older Apple devices using the 30-pin connection. Confirm that it charges, holds power, and includes the dock cable; if those basics are sound, this is an easy buy at A$130.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Fostex emerged in 1973 as the branded consumer and professional division of Foster Electric Co., Ltd., a Japanese loudspeaker manufacturer founded in 1949. Established to bring Foster's high-quality speaker components directly to dealers and customers, Fostex quickly gained international recognition through innovative products like the T20RP headphones and 6301 studio monitors. The brand's foundation rests on Foster's position as one of the world's largest OEM loudspeaker developers, employing tens of thousands across multiple countries and manufacturing millions of speaker units monthly.
The company built its reputation across three interconnected product categories: professional studio equipment, consumer headphones, and powered monitor speakers. Fostex became particularly renowned for pioneering RP (Regular Phase) technology, which delivers clear sound with high sensitivity and wide dynamic range—a signature that defines their headphones, microphones, and speaker designs. Beginning in 1978, the brand expanded into professional speaker development, eventually introducing the PM series of powered monitors and establishing itself as a trusted choice for recording studios, broadcast facilities, and serious home listeners.
Fostex occupies a distinctive middle ground in the audio market: neither ultra-premium boutique nor mass-market consumer, but rather a respected specialist brand with deep professional credentials. Their products appeal to recording engineers, studio owners, and discerning hi-fi enthusiasts who prioritize accuracy and reliability over luxury positioning. The 6301B monitor remains an industry standard after decades in production, while the T20RP headphones maintain popularity among studio professionals—testament to Fostex's enduring reputation for sonic integrity and engineering excellence.
