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.pe/products/705280939-s-m-s-l-su-1-mqa-mqa-cd-audio](https://www.desertcart.pe/products/705280939-s-m-s-l-su-1-mqa-mqa-cd-audio) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-17*
