At US$155, this FiiO K11 R2R sits just above the 75th percentile (US$148) of recent used listings, making the price slightly ambitious but not unreasonable for a unit in unknown condition. The median used price is US$134, with most listings clustering between US$125 and US$148, so you’re paying roughly US$21 over the median and US$7 over the top quartile.
The K11 R2R is well-regarded as one of the most affordable desktop R2R DAC/amps, offering a fully differential 24-bit resistor ladder, 1300mW balanced output, and multi-input flexibility (USB, coax, optical, Bluetooth) in a compact form. Its appeal lies in delivering genuine R2R topology at an entry-level price, a rare value in today’s market. If this listing includes the original power adapter and cable, and the unit shows minimal wear, it’s a solid buy for enthusiasts seeking budget R2R sound without the usual premium. Just confirm condition before committing, since “unknown” leaves room for hidden issues.
