US$159 is fair, not a steal, for a GCD-700 in unknown condition; it’s in line with the low-to-middle used market rather than a bargain-bin price. A fully working example with remote and clean operation can justify this, but if it turns out to need service, the value drops fast.
It’s still a worthwhile buy because this model is well-liked for its smooth, musical presentation and solid Burr-Brown-era DAC section, and good units have a strong following among vintage digital fans. The real upside is getting one that’s been kept original and functions properly, especially with the remote and a healthy carousel mechanism; age-related issues are the main watchout, so confirm disc loading, track access, and playback stability before committing.

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.
