INTRODUCING A FOLLOW-UP TO THE WELL-RECEIVED SU-9n, THE ALL-NEW SU-9n IS A HI-RES CERTIFIED DAC
S.M.S.L is a Hi-Fi audio brand specialising in high-quality premium desktop audio gears. Foshan ShuangMuSanLin Technology Co., Ltd, founded in 2009, located in Shenzhen, China, is a company that specialises in audio DAC, stereo headphone amplifiers, and power amplifiers. S.M.S.L presents the all-new SU-9n Hi-Res DAC that is compact and elegant. It is a fantastic DAC that provides exceptional sound performance and improves the listening experience. The S.M.S.L SU-9n has been certified to be Hi-Res Audio capable, according to the standards developed by the Japan Audio Association (JAS). It accomplishes its job and provides a clean and distortion-free sonic performance to acquire the desired sound output from your system stack. It is a feature-loaded DAC with an ESS Sabre DAC chip that delivers exceptional dynamic response. The S.M.S.L SU-9n also hosts an XMOS chip for USB control and a Qualcomm Chip for seamless wireless transmission. Sonically, the S.M.S.L SU-9n offers a trade-off for the MQA capabilities rather than being a simple SU-9 without it. In addition to possessing a broad and deep soundstage and a balanced yet dense presentation, the SU-9n provides something unique. The S.M.S.L SU-9n can be your companion for creating a desktop chain. With an S.M.S.L SU-9n Hi-Res DAC, you are sure to get the best possible audio experience.

FEATURES ESS SABRE DAC CHIP FUSED WITH ULTRA-LOW NOISE REGULATOR THAT DELIVERS DETAILED AND PRECISE SONIC PERFORMANCE
The most important aspect of a DAC is the DAC chips that they host and the power regulators to support those DAC chips. With this design consideration in mind, a team of engineers at S.M.S.L have structured the architecture of S.M.S.L SU-9n to accommodate high-performance power supply and ESS Sabre DAC chips. The S.M.S.L SU-9n features an industry-standard ES9038PRO Sabre DAC chip fused with an ES9311 ultra-low noise regulator that delivers detailed and precise audio conversion. The industry's highest-performance, ultra-low noise regulator, the ES9311, is designed to supply necessary reference voltages for ESS' 32-Bit SABRE DACs. The ES9311 ultra-low noise regulator (power supply) ensures low noise of 1Vrms, to push ES9038PRO to perform without generating distortion signals. The ES9038PRO is propelled to its utmost by the ES9311 ultra-low noise regulator (power supply), resulting in jitter-free audio reproduction. The S.M.S.L Su-9n performs incredibly well with this architecture and delivers exceptional performance when it comes to tonal balance, allowing all the frequencies across the frequency spectrum to shine through. The innovative design of the S.M.S.L SU-9n makes it possible for your music to be as natural as possible. It has a good amount of presentation with great details, and subtle nuances in your recordings shine through with the S.M.S.L SU-9n.

EXCEPTIONAL WIRED AND WIRELESS TRANSMISSION WITH XMOS AND QUALCOMM CHIPS WITH BLUETOOTH 5.0 RENDERING AND HIGH-END DUAL OP-AMPS THAT DELIVER OPTIMUM PERFORMANCE
The S.M.S.L SU-9n hosts an XMOS XU-208 8 Core chip with a comprehensive range of 32-Bit multicore microcontrollers that bring the low latency and timing determinism of the xCORE architecture. The XMOS XU-208 is a true 32 Bit audio processing chip that supports DoP (DSD Over PCM), Native DSD, 768kHz DSD512. The S.M.S.L SU-9n supports USB, optical, and coaxial connections as inputs with support for DSD transmission and DOP64 (DSD Over PCM). The S.M.S.L SU-9n supports DSD512 (Direct Stream Digital) and PCM 768kHz/32Bit (Pulse Code Modulation) for a Hi-Resolution audio source playback. The S.M.S.L SU-9n also hosts Qualcomm's latest Bluetooth chip QCC5125, that supports LDAC (24Bit/96kHz), aptX-HD (24Bit/48kHz), aptX (16Bit/44.1kHz), SBC (16Bit/44.1kHz), and AAC (16Bit/44.1kHz) audio codecs. Now, you may wirelessly stream music without worrying about signal loss. The Bluetooth 5.0 allows for low latency Hi-Res music playback without the annoyance of wires. The S.M.S.L SU-9n has three high-end dual op-amps OPA1612 that deliver optimum performance.

FREEDOM FROM NOISE AND DISTORTION WITH ULTRA-LOW PHASE NOISE AND OPTIMISED CLOCK PROCESSING TO ACHIEVE MINIMAL CLOCK JITTER
The term "clocking" in audio electronics refers to the mechanisms used to maintain sync with the primary audio clock and precise timing of several digital circuits, such as power supplies, high-speed signal processing, and modulation. All digital components must have the clock source: an internal reference system that allows that component to understand when it's time to do something with the audio samples it receives at its input. For instance, a DAC's primary function is to transform digital audio signals into analogue signals—voltages that power your speakers or headphones. It is important to time this procedure correctly to guarantee that the audio you hear accurately captures the musical occurrence. If the DAC doesn't convert audio samples at precisely the appropriate time, you hear a musical note that has been an artificially distorted version of the original studio recording. To eliminate this, the engineers at S.M.S.L included a CK-02 clock processing unit in S.M.S.L SU-9n's circuitry. It has a built-in shielded, low-noise power processing, improved power efficiency, low power consumption, and a THD+N of 0.00006%. This design architecture ensures the audio is transmitted free of distortion and jitter. The S.M.S.L SU-9n has a built-in shielded, low-noise power supply processing that improves power efficiency and lowers power consumption. Specially designed discrete component linear regulated power supply and multiple low noise regulated power supplies provide low noise power for analogue circuits.

EXQUISITELY DESIGNED WITH TFT LCD DISPLAY AND THOUGHTFUL INPUT OUTPUTS ALONG WITH REMOTE OPERABILITY AND USEFUL ACCESSORIES
The S.M.S.L SU-9n is a highly-compact DAC with a rugged form factor. It has an exquisite finish with a CNC machined aluminium alloy body. The S.M.S.L SU-9n is designed in such a way to look elegant with better heat dissipation. The mini-size design is very suitable for desktop use. The front baffle of the S.M.S.L SU-9n includes a knob that acts as a volume wheel, menu, and power on/off button. The S.M.S.L SU-9n has a 1.9-inch TFT LCD (Liquid Crystal Display) that lets you know the audio format, volume level, and sampling rate. Tempered glass on the LCD allows for more light transmission and a longer lifespan. The rear baffle consists of RCA output, Balanced output, Bluetooth antenna, Coaxial input, USB Input, and AC IN (Power Supply). These inputs/outputs are made of high-quality materials and are gold-plated. This setup enables you to create a desktop audio stack. The S.M.S.L SU-9n has a fully functional remote that allows you to change settings, toggle the menu, and increase or decrease volume. The remote uses two R03/AAA batteries. The S.M.S.L SU-9n comes with a Bluetooth antenna, the standard IEC power cable, a remote control, a USB cable, and the manual and warranty information.
