This is a fair ask, leaning a touch attractive: at US$163, it sits below the US$169 25th percentile of your recent comps and well under the US$200 median, so it’s priced like a legitimate buy rather than a stretch. It is not so low that it screams hidden problem, but it is cheap enough to deserve attention if you were already hunting this amp.
The appeal here is straightforward: the GFA-535 is a respected high-current stereo power amp with a reputation for grip, punch, and solid control, especially with tougher speakers. If the listing is genuinely clean and fully functional, the upside is a capable, old-school powerhouse at a price that leaves room for any needed servicing; just confirm basic health, because age-related maintenance is the main variable on gear like this.

ADCOM emerged in the 1970s as a family-owned American audio venture founded by audiophile Newt Channin, initially focusing on exceptionally musical moving-coil phono cartridges that set it apart from typical entrants. The brand quickly pivoted to electronics with the groundbreaking GFA-1 power amplifier in 1979, delivering 200 watts per channel and robust current for demanding speakers, propelling ADCOM into prominence during the high-fidelity boom of the 1980s and 1990s.
The company built its legacy on high-performance amplifiers, including the Nelson Pass-designed GFA-555 that garnered worldwide acclaim, alongside AV tuners, preamps, and multichannel power amps like the GFA-6000 tailored for home theater. While early roots lay in phono gear, ADCOM specialized in electronics offering superior sound quality without extravagant pricing, eschewing speakers, headphones, or extensive cabling lines.
Positioned firmly in the mid-fi realm, ADCOM defined accessible high-end audio for discerning buyers, blending value and performance that rivaled pricier competitors. After challenges and ownership shifts—including a Thai firm and a faltering 2010 relaunch—the brand staged a robust comeback in 2024 under J&B Distribution, reviving classics like the GFA-555ms alongside modern integrated amps and preamps, reclaiming its spot among savvy audiophiles seeking reliable, soul-stirring sound.
