The asking price of US$75 sits just below the median of US$70 from your ground truth data, making it a fair deal for a used SMSL SU-1 DAC rather than a bargain or overpriced listing. Since it falls between the 25th percentile (US$64) and the 75th percentile (US$85), it aligns well with typical used market values for this model, offering solid value without extremes.
This DAC is well-regarded for its clean dynamics, versatile input options including USB, coax, and optical, and rare MQA support at an entry-level price. Its AK4493S chip delivers excellent upper-level detail, making it ideal for setups that need more clarity in the high frequencies. A clean, original-owner listing at this price represents a timely buying opportunity for budget enthusiasts seeking reliable performance without compromise.
