Cleans up recordings, when converting analog audio to digital signals, time jitter occurs, causing transient signals to blur over time As a result, our ears can no longer tell where a certain signal is located By comparing recorded music and live performances, a single sound is created The performance of "playing" is not noticeable MQA eliminates this distortion and creates a true 3D sound field that is different from previous sounds - 2. Enclosing sound: In MQA, after removing recording jitter, something called "musical jitter" is used Origami Mprocess, this clever device manages large resolution files easily and is compatible with all services and playback devices - MQA CD Support: Compatible with CD player + MQA compatible DAC, the digital output (optical or coaxial) of the CD player can be supplied to the MQA compatible DAC It is a coder The MQA decoder can restore and play back the original high-resolution audio signal SMSL SU-1 is compatible with MQA CD - AKM AK4493S: The SU-1 adopts the latest AKM DAC chip, AK4493S, achieving distortion of 0.00013% or less USB In: Compatible with Windows7/8/8.1/10/11(driver required), Mac 0S X10.6+, Linux (driverless), Android, i0s ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C1Y7C9HH | | Amazon Bestseller | #35,866 in Electronics ( See Top 100 in Electronics ) #29 in Digital-Analog Converters | | Brand Name | Fanmusic | | Compatible Devices | Earphones, Headphones both | | Customer Reviews | 4.3 4.3 out of 5 stars (1,676) | | Interface | USB | | Item Dimensions L x W | 9.6L x 7.8W cm | | Item Weight | 195 Grams | | Manufacturer | SMSL | | Model | SU-1 | | Number of Channels | 2 | | Number of Pins | 4 | | Part Number | SU-1 | | Warranty Description | 1 Year Mecha Warranty | ## Product Details - **Brand:** Fanmusic - **Interface Type:** USB - **Number of Channels:** 2 - **Number of Pins:** 4 - **Product Dimensions:** 9.6L x 7.8W cm ## Images ![S.M.S.L SU-1 MQA MQA-CD Audio Decoder AK4493S XU316 768kHz/32Bit DSD512 Hi-Res DAC - Image 1](https://m.media-amazon.com/images/I/21AA7hVlMAL.jpg) ## Questions & Answers **Q: When I hook it up to play there is music for a second or two and then no music for a second or two. This repeats itself over and over again. Ideas?** A: I do not have that problem with this device, HOWEVER, I do have that very same problem with another SMSL dac ( M500 MKII), and I have not been able to figure out why this happens. I do not use Windows, and I only play wav files with Linux based software, and Linux operating system. Make your own conclusions. **Q: how come the output voltage is so low when I connect it to the optical on my TV? I thought the output was suppose to be 2 Vrms.** A: only tried whit coaxial in rca out **Q: Without a separate power input, how much faster does the battery drain on the cell phone?** A: It consumes very low energy. I don't use it via USB. I haven't tested it. **Q: I'd like to listen to one of those new MQA-encoded CDs. Will the optical output of my legacy CD player pass the MQA-encoded signal to this SMSL?** A: Yes, because the SMSL is reading, converting the signal and your legacy CD player is functioning as a transport only. ## Frequently Bought Together - S.M.S.L SU-1 MQA MQA-CD Audio Decoder AK4493S XU316 768kHz/32Bit DSD512 Hi-Res DAC - TOSLINK – Optical Audio Cable – 3ft – Designed in Germany – Fiber Optic Cable for Soundbar, SPDIF Digital Optical Audio Cord – for Sound Bars, Stereo Systems, amps, Xbox One or PS4 – by CableDirect - SMSL PO100 PRO MQA DDC XMOS XU316 Digital to Analog Audio Converter Type-C USB Input IIS/Optical/Coaxial Output Mini Portable USB Interface for Phone/PS5/Switch/TV --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/730328152-s-m-s-l-su-1-mqa-mqa-cd-audio](https://www.desertcart.be/products/730328152-s-m-s-l-su-1-mqa-mqa-cd-audio) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-06-14*
