This is a respected desktop DAC/amp combo, but the ask is on the high side for the used market. With recent comparable listings centered at US$239, and the upper quartile at US$250, US$325 sits clearly above typical value and only makes sense if the unit is especially clean, well-documented, and includes desirable extras.
The DX7s is still appealing for its very solid DAC section, balanced outputs, and all-in-one convenience, so a good example can be a smart buy for a compact system. That said, at this price the seller should be delivering more than just “works fine” — look for original packaging, remote, cables, and proof it has been carefully kept; otherwise, it’s a wait-for-a-better-priced example situation.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
