This US$128 asking price for the used Topping E50 is a strong deal, landing well below the 25th percentile of US$150 from your recent comparable listings. With the median at US$150 and the 75th percentile at US$152, you are securing this flagship-sounding entry-level DAC for roughly US$22 less than the typical market floor, making it an excellent buying opportunity for enthusiasts.
The E50 remains well-regarded for its ES9068AS chip performance, delivering distortion as low as 0.00009% and 124dB SNR in a compact desktop form. It handles PCM up to 768kHz and native DSD512, offering flagship audio quality at an entry price. Since this price is a genuine bargain, the lack of specific condition details is less concerning; the performance upside and timing make this a smart grab for anyone needing a high-spec USB DAC with coax/optical inputs.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
