Review: Byłem sceptyczny. Niepotrzebnie - Trochę nie wierzyłem, że tak tanie urządzenie może coś poprawić. U mnie jakość dźwięku z podstawowego streamera (TagaHarmony) zdecydowanie się poprawiła - dzięki głębszym basom i większej selektywności. ## Features - USB supports MQA:1.Clean up the recording 2.Encapsulate the sound - Support MQA CD:CD Player + MQA- Enabled DAC,Your CD player's digital output (optical or coaxial) can be fed to an MQA de coder.

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 ### ⭐⭐⭐⭐⭐ Roll of the dice for better sound. *by M***Z on 28 February 2026* ### ⭐⭐⭐⭐⭐ Byłem sceptyczny. Niepotrzebnie *by A***G on 28 February 2026* Trochę nie wierzyłem, że tak tanie urządzenie może coś poprawić. U mnie jakość dźwięku z podstawowego streamera (TagaHarmony) zdecydowanie się poprawiła - dzięki głębszym basom i większej selektywności. ### ⭐⭐⭐⭐⭐ Excellent, rapport qualité prix imbattable *by P***E on 31 May 2025* Très bon. Bons timbres, très dynamique et clair. Bonne profondeur de scène sonore. Il a remplacé un Topping E30 et est nettement meilleur. L'avantage est qu'il n'y a pas de filtres, ni de suréchantillonnage avec une lecture CD. Comme on dit en anglais, "Less is More". Il a de bonnes basses, bien tenues, mais pas extra profondes. Il manque un peu de medium. J'ai essayé ensuite le D6s qui avait un son dur dans les aigues et artificiel sur mon installation. Donc, je garde le SU-1, qui est imbattable en rapport qualité prix. Il faut lui associer une bonne alimentation linéaire et de bons câbles pour en tirer le maximum. La puce AK produit des sons très naturels. Je n'ai pas du tout aimé le son de la puce ESS sur le D6s. ## 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.ph/products/705280939-s-m-s-l-su-1-mqa-mqa-cd-audio](https://www.desertcart.ph/products/705280939-s-m-s-l-su-1-mqa-mqa-cd-audio) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-14*
