Unboxing and First Impressions
The unboxing experience was premium, with a box-within-a-box design. The included remote felt high-quality and substantial, suggesting a focus on build quality throughout the product. The unit itself sits on three aluminum feet, adding to its elegant appearance.
A standard USB cable was included, a practical addition. The overall first impression was one of sophisticated design and robust construction, hinting at a premium audio experience.
Rear Panel Connectivity and Features
The rear panel is symmetrically designed, showcasing a range of digital inputs: USB, AES/EBU, SPDIF, and optical Toslink. Playback Designs' proprietary PlayLink interface is also present, along with a network port of unknown function.
Importantly, the MPD-8AI includes balanced and unbalanced analog inputs and outputs. This dual functionality sets it apart as a true hybrid DAC/preamp, providing flexibility in system integration.
Front Panel and User Interface
The front panel is minimalist, with two display screens. The top screen shows the input signal and sampling rate, while the bottom shows the volume level. The analog volume control is described as quiet and responsive.
The unit's settings menu, accessible via the remote control, allows for independent input switching and phase adjustment. Power on/off is controlled via a physical button on the device itself.
Internal Design and Technology
Inside, the unit boasts three toroidal transformers providing independent power to the left and right channels and digital processing. This dual-mono design minimizes crosstalk and enhances audio fidelity.
Playback Designs uses a proprietary decoding method, converting all signals to a one-bit delta-sigma DSD format before upsampling and converting to analog. This process aims to achieve a more natural and analog-like sound signature.
Sound Quality and Performance
The reviewer praises the sharp imaging and separation, noting the balanced tonal presentation. The mids and lows are highlighted as particularly pleasing, with punchy bass and textured mids.
Compared to the original MPD8, the AI version is described as more delicate and detailed, with a greater sense of air and space. The reviewer considers the analog volume control a significant strength, surpassing many DACs marketed with similar preamp functionality.
Strengths, Weaknesses, and Final Verdict
The MPD-8AI excels as both a high-resolution DAC and a high-quality preamp. Its analog volume control is a key differentiator, allowing for detailed and dynamic playback at all volume levels. The build quality is exceptional, and the sound is characterized by a natural, analog-like presentation.
The lack of an external clock input and I2S input are cited as minor shortcomings, limiting flexibility and compatibility. However, these are relatively minor drawbacks, especially considering its overall performance.
