The SMSL PO100 Pro is widely respected as a top-tier USB DDC (digital-to-digital converter) that cleanly extracts audio data from sources like PCs or game consoles before feeding it to a dedicated DAC. It features the robust XMOS XU316 chip, supports DSD512 and PCM 32-bit/768kHz, and delivers impressive noise performance (123.4dB SINAD), often outperforming many entry-level DACs in pure digital interface metrics. At this price, it’s a no-brainer upgrade for anyone building or refining a high-res audio chain.
