Compared with a generic modern 60W-per-channel amp at this money, US$141 is a fair-to-good buy for an SE120, not a steal but comfortably in the right zone. Recent comparable used examples have shown up around US$135 and US$129, with an older MSRP of US$350, so this asking price sits close to the typical market rather than above it.
What keeps it appealing is the Hafler/MOSFET voicing: these are respected for a smooth, slightly tube-like presentation, good dynamics, and enough current to make honest use of efficient speakers or a modest stereo system. At this price, a clean, working unit with no drift, scratchy controls, or missing feet is worth a look; the main buyer focus should be condition and proof it has been serviced or at least runs quietly, since age is the real variable here.
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.
