Hidizs S3 Pro Portable MQA DAC AMP is the new model of the S3 series which was a simple Type-C DAC dongle. S3 Pro has a better DAC chip, obviously, ESS9281C Pro which also supports MQA decoding. Lately, we see many makers using this DAC chip for example Hilidac Atom 2, Questyle M12, and THX Onyx.
Hidizs S3 Pro is 0nly 0.79 inches (20mm) in diameter and 3.54 inches (90 mm) in length. About the size of a US penny – a tiny coin.
Mixed Braiding of 2 core high purity silver + 2 core OFC wires (60 strands each). Silver wires make for a brighter and cleaner sound quality. OFC wires add smoother and gentler performance. This is Hidizs’s claim, not mine. Does cable matter? 🙂
Hidizs S3 Pro has integrated molding aluminium alloy housing. Has wire control for earphones with mic support. PCM support up to 32bit/384kHz, native DSD128 and 8X MQA support (renderer). S/N Ratio is -110dB and SNR is +130dB.
Hidizs S3 Pro can be used with Windows, Mac OS, iPad OS, iOS and Android. For iOS users, the Lightning OTG cable has to be purchased separately, no adapter is included in the box. Comes in two colors, black and grey.
The price of the Hidizs S3 Pro is 55$.
