Unknown condition at US$225 puts this right around the market’s middle for a used DX7s, versus a US$232 median and a US$206–US$247 typical band. That makes it a fair asking price rather than a steal, but still solid if the unit checks out and the seller can verify clean operation.
The DX7s is well liked as a compact all-in-one DAC/preamp/headphone amp with very competent measurements and enough flexibility to suit a desktop or secondary system. At this price, the real upside is getting a proven, versatile unit without paying new-gear money; just confirm remote, power supply, and inputs all work properly, since any missing pieces would push this from fair to merely acceptable.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
