Priced at US$400, this used SMSL SU-9 sits right at the 75th percentile of recent comparable listings, making it an ambitious but not unreasonable ask compared to the median of US$300. While new retail prices historically hovered around US$439–US$449, the current asking price reflects a modest discount from original cost rather than a deep bargain, yet it stays within the established upper range of US$175–US$400 for this model.
The SU-9 remains a well-regarded desktop DAC for its ESS9038 Pro performance, MQA decoding, and top-tier Bluetooth 5.0 with UAT, delivering excellent staging and resolving power without premium pricing. At US$400, it’s a worthy buy for enthusiasts seeking a balanced, pure-sounding DAC with strong inputs (USB, Optical, Coax, BT) and outputs (XLR, RCA), especially if the unit is in clean, original-owner condition with accessories like the remote included. No major caveats apply unless condition is questionable.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
