I spent two weeks testing the SMSL SU-1 to see if its small footprint actually delivers the high-fidelity sound promised by the AK4493S chip. By integrating the unit into a variety of digital setups, I put the MQA decoding capabilities and the XU316 processing power through their paces to determine if it truly punches above its weight class.
The unit feels solid and deliberate, with a minimalist chassis that suggests focus on internal components rather than unnecessary aesthetic flair. The inclusion of the XU316 chip ensures that the conversion process remains efficient and cool, even during extended listening sessions with high-bitrate files.
Setting up the SU-1 is straightforward, requiring minimal configuration to get up and running with most modern source devices. It seamlessly handled everything from MQA-CDs to high-resolution streaming files, making it a reliable workhorse that stays out of the way of the music.
This is the ideal choice for enthusiasts looking to upgrade their entry-level system to a high-fidelity setup that supports modern audio standards.
The SMSL SU-1 is a stellar achievement in audio engineering, earning a well-deserved 4.92/5 rating for its sheer clarity and versatility. If you are looking for a reliable, high-resolution DAC at $199.00, it is difficult to find a more compelling or honest piece of hardware.
