Hafler’s Model 100 sits in that classic no-nonsense, value-minded preamp territory, and at US$295 this lands a bit above the US$250 median but still comfortably below the US$375 upper quartile. That makes it a fair asking price rather than a bargain-bin steal or an inflated ask.
The appeal here is straightforward: solid vintage build, clean signal-path simplicity, and the kind of musical, practical preamp that has kept Hafler gear in demand. If the unit is clean, fully functional, and unmolested, this is the sort of purchase that can make sense for a second system or a restoration-minded main rig. At this price, the main thing to confirm is proper operation of all controls and switches, since age-related wear matters more than cosmetics on gear like this.
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.
