This is a buyer’s market for this amp at the moment, and US$250 lands a touch above the US$235 median but still inside the usual used window of US$227–US$242. That makes it a fair, slightly firm ask rather than a bargain, so it’s worth considering if the unit is clean and properly working.
The Hafler 100 has the kind of no-nonsense, high-current character many vintage hi-fi fans still like: solid drive, good control, and an honest presentation that pairs well with efficient speakers or a beefier preamp. At this price, the appeal is in getting a respected classic in known-good condition, ideally with original packaging or a documented service history; if it’s been serviced recently, that would support the ask nicely.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Hafler is an American hi-fi brand rooted in the postwar audio hobbyist era. It traces back to David Hafler, who co-founded Acrosound in 1950 and later helped launch Dynaco in 1954; he then founded the David Hafler Company in 1972, carrying forward his long-standing focus on accessible, high-performance audio. The brand is closely associated with the U.S. DIY-to-assembled tradition that shaped early hi-fi culture.
Hafler became best known for amplifiers and preamps, especially solid-state MOSFET power amps and matching line-stage products. Classic models such as the DH-101, DH-110, DH-200, DH-220, DH-500, and XL-280 established the name, and the company also had a role in speaker design during the broader Hafler/Dynaco era. While not a turntable, DAC, or headphone specialist in its classic identity, the brand’s legacy is strongest in amplification.
In the market, Hafler sits more in the respected value and vintage-audiophile lane than the luxury tier. Its appeal comes from engineering credibility, straightforward designs, and a reputation for honest sound and reliability rather than exotic finishes or ultra-premium pricing. Today, it is best thought of as a classic hi-fi name with strong collector interest and enduring brand recognition among enthusiasts.
