US$250 is a fair-to-good price, sitting below the US$270 median and comfortably above the US$200 25th-percentile mark for comparable used Hafler listings. It is not a bargain in strict percentile terms, but the price is justified if the cleaning and testing are genuine.
The Model 100 is a straightforward, well-regarded control preamp with a useful MM phono stage, sensible line inputs, tape monitoring, and a clean, low-distortion presentation. Hafler’s no-frills engineering and solid build make these enjoyable partners for vintage power amplifiers, and this one’s reported clean condition is a real positive. Before buying, confirm both channels, controls, phono, and tape functions work quietly; otherwise, US$250 leaves little room for repair.
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.
