At US$135, this looks fair to slightly strong rather than cheap; the 9130 is an older but still respected Hafler MOSFET design, and comparable used chatter puts it around US$140–US$200, so this asking price sits at the low end of the usual range. The age does matter here, because you’re buying a late-era vintage amp rather than a modern replacement model, but the model’s reputation and pricing suggest the market still values it.
What makes it worth a look is the honest, clean 65 watts per channel, low distortion, and the ability to run as a stereo amp or bridge to mono, which gives it flexibility for real-world systems. It’s a good fit if you want a compact, no-nonsense amp with a reputation for clear, controlled sound; at this price, a clean, original unit with working controls and no hum is a solid buy, especially if the seller can confirm it powers up quietly and hasn’t been butchered.

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.
