Timing matters a bit here because this is a mature, well-known DAC era rather than a new release, so you’re buying on reputation and condition, not upgrade hype. At £598, it sits above the £448 median and over the £634 75th percentile boundary? Actually it is below that upper quartile, so it reads as slightly ambitious but not outrageous for a sought-after piece in a strong listing.
What makes it interesting is the D90’s long-standing appeal: clean, detailed conversion, very low noise, and the kind of transparent presentation that pairs well with revealing amps and headphones. If it’s genuinely tidy, includes the box/remote/power supply, and has no signs of owner-abuse, it can still be a sensible buy for someone who wants a compact, respected DAC rather than chasing the newest model. At this price, I’d mainly want confidence on provenance and completeness.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
