Technical Specifications and Architecture
At the heart of the DO200 Pro lies Cirrus Logic's advanced CS43131 audio decoding chip. SMSL's innovative implementation utilizes 12 of these chips in a meticulously designed circuit, achieving a remarkably low non-weighting distortion level of 0.00006% (-123dB). This engineering feat sets a new benchmark for audio clarity and fidelity in its price range.
The DAC is built around the third-generation XMOS XU-316 chip, enabling support for an impressive array of high-resolution audio formats. It can handle PCM signals up to 32-bit/768kHz and DSD up to DSD256, ensuring compatibility with virtually all modern high-resolution audio sources. For aficionados of master-quality audio, the DO200 Pro offers full MQA decoding capabilities, including support for MQA-CD, allowing users to experience studio-quality sound from compatible sources.
SMSL has spared no expense in component selection, incorporating five high-end OPA1612 operational amplifiers known for their low noise and distortion characteristics. The attention to detail extends to the use of audiophile-grade resistors and capacitors throughout the signal path, ensuring that every element is optimized for superior sound quality.
The fully balanced circuit design offers both balanced (XLR) and unbalanced (RCA) outputs, catering to a wide range of audio setups and allowing users to choose the optimal connection method for their system. This dual-output capability also provides flexibility for future system upgrades.
The DO200 Pro boasts an impressive array of connectivity options, making it a versatile centerpiece for any audio system:
This comprehensive set of inputs ensures that the DO200 Pro can accommodate virtually any digital audio source, from computers and smartphones to CD players and streaming devices to even gaming as SMSL really showed off the compatibility with the Nintendo Switch and Sony PS5.
A fully fitted display screen provides easy access to settings and real-time playback information, allowing users to monitor and adjust the DAC's performance on the fly. The included full-featured remote control adds convenience, enabling users to make adjustments from their listening position or with the included remote.
The DAC also features a pre-mode, which allows for seamless integration into various audio systems. This mode can potentially eliminate the need for a separate preamplifier in some setups, simplifying the signal chain and potentially improving overall sound quality.
SMSL has paid careful attention to often-overlooked aspects of DAC design that can significantly impact audio quality:
These features work in concert to achieve the DO200 Pro's exceptional signal-to-noise ratio and overall audio performance. The DAC's credentials are further bolstered by its Japan Audio Society (JAS) Hi-Res certification, assuring users of its capability to reproduce high-resolution audio with utmost accuracy.
Assessment In listening tests, the DO200 Pro demonstrates a clean, neutral sound signature without noticeable coloration. It presents a wide, well-defined soundstage with precise imaging, allowing listeners to easily locate instruments and vocalists within the audio space. The DAC's low noise floor contributes to excellent detail retrieval, revealing subtle nuances in recordings that might be missed with lesser equipment.
Bass response is tight and controlled, with good extension and impact when present in the source material. The midrange is particularly well-rendered, with vocals and instruments sounding natural and unforced. High frequencies are extended and airy without becoming harsh or fatiguing, even during long listening sessions.
While differences between top-tier DACs are becoming increasingly subtle, the DO200 Pro holds its own against more expensive competitors, offering a level of performance that belies its modest price point.
At a price point of $400, the DO200 Pro offers exceptional value, especially considering it's $90 cheaper than its predecessor. This combination of improved specifications and reduced cost makes it an attractive option not only for those looking to upgrade from entry-level DACs but also for owners of the previous model seeking enhanced performance.
While the included remote control is functional, it doesn't introduce any new features compared to previous SMSL models. Some users might appreciate a more premium feel or additional customization options.
The display and user interface remain largely unchanged from the previous model, which may disappoint those hoping for a more modern aesthetic or enhanced graphical display. An updated UI could potentially improve the user experience and make navigating the DAC's many features more intuitive.
The SMSL DO200 Pro represents a significant advancement in DAC technology, offering a compelling combination of cutting-edge features, meticulous design, and exceptional audio performance. Its improved specifications, versatile connectivity options, and reduced price point make it an attractive option for a wide range of audio enthusiasts.
For those seeking to elevate their listening experience without breaking the bank, the DO200 Pro stands out as a formidable contender in the competitive DAC market. It successfully bridges the gap between high-end performance and affordability, making it a worthy consideration for anyone looking to upgrade their digital audio chain.
While there's always room for minor improvements, particularly in the user interface department, the core performance and value offered by the DO200 Pro are undeniable. SMSL has once again demonstrated their ability to push the boundaries of what's possible in this price range, cementing their position as a leader in the affordable high-end audio market.
