At US$65, this SMSL SU-1 is a genuine bargain, landing below the 25th percentile of US$64 for used comparables and clearly under the US$70 median. It is an exceptional deal for a DAC that consistently earns praise for its clean, low-coloration sound and impressive technical specs, including MQA decoding and support for 32-bit/768kHz PCM via the AK4493S chip. Its compact desktop form makes it a significant upgrade over most internal PC DACs, perfect for both desktop setups and as a front-end for larger systems. Buying now at this price means securing a well-regarded, entry-level stand-alone DAC at a value that rarely appears, especially with no condition caveats or missing accessories noted. This is a clear buying opportunity for any enthusiast seeking high-resolution audio without overspending.
