Just had an 1990s DAT player refurbished, brought back from the dead after it had spent thirty years in the garage, now it plays perfectly but it had a somewhat compressed sound. This DAC has one of the very latest/best chip sets usually found in units at ten times the price, the DAC in the DAT is thirty years old so could benefit from the latest tech to give it a boost. Some people think all DACs are the same but they are clearly not, a listening test shows this very clearly, just as all headphones don’t sound alike. I have six DACs, some are good, some are not so good and it does not always relate to cost. A have a Fosi which is ok as a headphone DAC and pre amp which is ok, warm sounding but lacking clarity, a Beyerdynamic slightly better but not enough for the additional cost, a Chord Mojo which is very good used between an ipad and twin rca cables to an amp, a Prozor for 5.1 sound from a modern tv to ancient analogue cinema amp which was very cheap but sounds great and now this which sounds brilliant, better than the Chord but at about a fifth of the price. A good DAC puts air and soundstage into the music, separates the instruments and gives clarity to bass and treble. This one has opened up the sound of this DAT player, giving a clearer sound, very pleased with the result for such a low cost item. Also as the DAT is optical cable and the CD player, also from the 90s, is coaxial digital, this unit can take both items and you can switch between them using the button on the front. Review: Progress - Like most people, my interest in sound devices and recordings is simply about getting as close as possible to the sound of a great performance of the music to which I listen. Bach, Bacharach, Basie, whatever. And this super little sound device constitutes very siginificant progress in that quest. Connected by USB to my PC it takes PCM and DSD files, converts them and sends an analogue signal to my desktop amp (Douk Audio T6). I listen to the output on Sony MDR 1 headphones. Like everyone with good new equipment I hear things differently and more clearly on recordings I have loved for years. Dynamics, attack and decay of notes, balance within ensembles, tonal nuance and so on. The S.M.S.L. SU-1 makes it all possible. Set up and operation are simplicity itself and the Roon music library/player connected immediately. (The only advisory I offer is to ensure you download and install the relevant driver to facilitate ASIO again easily done from the SMSL website) All this for a derisory price compared to regular hifi equipment. The only regret I have is that I now won't be trying out anything else for some time to come. ## Features - USB supports MQA: 1.Clean up the recording, When the analog sound is converted to a digital signal,time blurring will occur, blurring transient signals over time. . MQA can eliminate this distortion and create a true 3D sound field, which is different from any sound you have ever heard. 2.Encapsulate the sound Once the blur in the recording Is removed,MQA will use what we call a "musical origamiMprocess,Cleverly makes this large resolution file easy to manage. - Support MQA CD:CD Player + MQA- Enabled DAC,Your CD player's digital output (optical or coaxial) can be fed to an MQA decoder. - The MQA decoder can restore the original high-resolution signal heard in the studio and confirm it, using the authentication signature.SMSL SU-1 support MQA CD. - AKM AK4493S :SU-1 utilizes the latest AKM DAC chip,AK4493S, for achieving a distortion lower than 0.00013% - USB In:Compatible with Windows 7/8/8.1/10/11 (driver is required),Mac 0S X10.6+, Linux(driverless), Android, i0s ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C1Y7C9HH | | Best Sellers Rank | 17,207 in Electronics & Photo ( See Top 100 in Electronics & Photo ) 73 in Digital-Analog Converters | | Brand | Fanmusic | | Compatible Devices | Personal Computer | | Country Of Origin | China | | Customer Reviews | 4.4 out of 5 stars 1,702 Reviews | | Included Components | no | | Interface | Coaxial, Optical, USB | | Interface type | Coaxial , Optical , USB | | Item Dimensions L x W | 9.6L x 7.8W centimetres | | Item Weight | 195 Grams | | Manufacturer | SMSL | | Manufacturer Part Number | SU-1 | | Material | Copper | | Model Number | SU-1 | | Mounting Type | Wall Mount | | Mounting type | Wall Mount | | Number of Channels | 2 | | Number of Pins | 8 | | Number of channels | 2 | | Number of pins | 8 | | Product Warranty | Warranty for non-human damage within one year, repairs after one year at your own expense. | | Product dimensions | 9.6L x 7.8W centimetres | | Smart Home Compatibility | Not Smart Home Compatible | | Unit Count | 1.0 count | ## Product Details - **Brand:** Fanmusic - **Interface type:** Coaxial, Optical, USB - **Mounting type:** Wall Mount - **Number of channels:** 2 - **Number of pins:** 8 ## Images ![SMSL 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) ![SMSL SU-1 MQA MQA-CD Audio Decoder AK4493S XU316 768kHz/32Bit DSD512 Hi-Res DAC - Image 2](https://m.media-amazon.com/images/I/41YWk85tRmL.jpg) ![SMSL SU-1 MQA MQA-CD Audio Decoder AK4493S XU316 768kHz/32Bit DSD512 Hi-Res DAC - Image 3](https://m.media-amazon.com/images/I/61Fh5P3jQHL.jpg) ![SMSL SU-1 MQA MQA-CD Audio Decoder AK4493S XU316 768kHz/32Bit DSD512 Hi-Res DAC - Image 4](https://m.media-amazon.com/images/I/51VXAcljlAL.jpg) ![SMSL SU-1 MQA MQA-CD Audio Decoder AK4493S XU316 768kHz/32Bit DSD512 Hi-Res DAC - Image 5](https://m.media-amazon.com/images/I/61OH+PEhn8L.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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Brilliant Sound, Superb Value *by J***N on 4 March 2025* Bought this is on review recommendations.

Actually, it's astonishing. Technically there are better DACs, but you can probably only measure the difference with professional equipment. Audio Science Review concludes "SMSL cuts the functionality to the minimum many need, to have high quality conversion of digital to analog for multiple inputs. Performance is superb for the cost, as it provides full transparency to the source. It proves that performance requires great engineering skill, and not a ton of money. A lesson that I hope one day high-end audio companies and their customers appreciate." I have it linked to a Pi2Aes (re-clocker linked to a Pi NAS music server) for my digital music catalogue and Web Radio, including MQA tracks. There's no volume control, which I rather miss, but that is available from the next stage (amp), so it outputs a good 2v. I'd prefer balanced inputs/outputs, but with this performance, who cares? This replaced a much larger DAC with multiple inputs, with greater functionality and lower cost. Did I mention how small it was? Astonishing. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/523773336-smsl-su-1-mqa-mqa-cd-audio-decoder-ak4493s-xu316](https://www.desertcart.tw/products/523773336-smsl-su-1-mqa-mqa-cd-audio-decoder-ak4493s-xu316) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-06-23*
