The US$550 asking price is fair, sitting just US$10 above the median of US$540 from your recent comparable listings and well within the tight US$535–US$545 range. While external market data shows older unserviced units often trade lower around US$200–US$300 and a serviced one for US$300, this specific listing aligns closely with the current median for used Hafler XL-280s in your database, making it a reasonable entry point rather than a bargain or an overpriced risk.
The XL-280 remains a highly regarded solid-state amplifier known for its 145 watts per channel into 8 ohms and robust 400-watt mono bridged capability, making it excellent for driving demanding speakers or subwoofers. Its “Excelinear” design delivers clean, uncolored power with minimal distortion, and many owners value its durability and straightforward, repair-friendly topology. If this unit is in unknown condition but priced at fair market value, it’s a solid buying opportunity for enthusiasts who can service it themselves or appreciate its raw performance potential.

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.
