At US$600, this is a bit above the usual used lane for a D90 LE, where recent secondhand asks cluster more around the US$400–US$500 range and only tougher-to-source or especially clean examples push toward US$600. That makes this an okay buy only if it’s notably tidy, well-documented, and complete; otherwise it reads a touch ambitious rather than a standout deal.
The upside is real: the D90 LE is a respected, very transparent DAC with strong measured performance, flexible inputs, and balanced outs that still compete well with newer units. If it includes the remote, box, and original accessories, and the seller can confirm stable operation, it’s still a sensible pick for someone wanting a high-end digital front end without paying new-retail money.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
