The D7 is a DAC from Audiolab built around an ESS ES9038Q2M chip with very wide digital format support. It sits at the compact, desktop end of Audiolab's electronics range, aimed at adding a serious converter stage to an existing source and amplifier setup rather than anchoring a system on its own.
Key specs that matter
It handles PCM up to 32-bit/768kHz and DSD512, an unusually wide format ceiling that covers essentially any file a typical digital library is likely to contain, including high-resolution downloads well beyond CD quality. Output impedance is 120 ohms for both balanced and single-ended outputs. Signal-to-noise is 115 dB via RCA and 117 dB via XLR, both strong figures for a converter at this size and price. Distortion is under 0.001%. At 180 x 208 x 56 mm and 1.42 kg it is a compact desktop-scale unit that will sit comfortably beside a laptop or streamer without dominating the desk.
Sound and use context
Expect a clean, low-distortion presentation typical of a modern ESS-based DAC, with the wide format ceiling covering the great majority of digital libraries - a listener with high-resolution downloads or DSD material in particular will find this converter has genuine headroom to handle it without downsampling.
Pairing
Both balanced and single-ended outputs suit either type of preamplifier without a gain shortfall, so integration should be straightforward regardless of what the rest of the system already uses.
Alternatives
Audiolab's broader source range, including its CD players, offers alternatives for a system built around different source formats, worth considering if physical disc playback remains part of the collection alongside digital files. Audiolab has built a long track record with ESS Sabre-based conversion chips across its DAC range, and the D7 represents the brand's compact, desktop-oriented take on that same chip family. Because the unit accepts both balanced and single-ended connections at matched impedance, it should integrate cleanly into systems built around either convention without needing an adapter or additional gain stage to compensate for a mismatch. The compact chassis leaves no room for a headphone output, so this unit should be understood purely as a line-level DAC rather than a combined DAC and headphone amplifier some competitors in this size class also offer. The absence of a headphone stage keeps the unit focused and affordable, which is a reasonable trade-off for anyone who already owns a separate headphone amplifier or intends to use this purely as a line-level source for a larger system.
