Ambitious ask: at USD 299, it sits above the 75th percentile of the recent comp set at USD 272, versus a median of USD 245 and a 25th percentile of USD 218. For a used preamp, that means this is priced at a premium rather than a bargain.
That said, the DH-100 is a respected, straightforward linestage with a good reputation for clean, unfussy sound and useful flexibility, so a strong example can still justify some extra spend. It’s most appealing if the cosmetics are excellent, the controls are quiet, and it’s been properly serviced; with gear this old, condition and maintenance matter more than the badge.
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.
