Our Thoughts RADAR AI

This US$800 asking price sits exactly at the median of the seven recent comparable USD listings for the Audio-GD R-28, marking it as a fair deal rather than a bargain or an ambitious overprice. The R-28 is a well-regarded, all-in-one R-2R NOS/OS ladder DAC and balanced headphone amplifier that enthusiasts prize for its unique discrete ladder architecture and massive power output (up to 19V RMS). It functions seamlessly as a DAC, preamp, and amp, offering a versatile, high-value solution that combines the strengths of Audio-GD’s mid-range decks and amps into one chassis.

The timing is solid because the R-28 remains a distinct, generation-defining product in the R-2R space, with no direct successor that fully replicates its specific ladder implementation and ACSS output options. At a fair median price, this is a genuine buying opportunity for anyone seeking a fully discrete, high-power DAC/amp without the modern chip-based compromises. Unless the condition is questionable or accessories are missing, there are no material caveats to raise; the R-28’s robust build and unique sound make it a worthwhile investment at this price point.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
