Unboxing and First Impressions

The Apos & Geshelli Merlin DAC arrived in its packaging, and the first thing that struck me was its compact size. It's surprisingly small, which is a plus for those with limited desk space. The unit itself boasts a unique, open skeletal design, showcasing its internal components. This design choice adds a visually appealing element that distinguishes it from other DACs.

Initial impressions suggest a well-built device, although concerns about the longevity of the plexiglass plates used in its construction came to mind. While aesthetically pleasing, plexiglass is prone to scratches and dust accumulation, potentially impacting its appearance over time.

Technical Specifications and Performance

Under the hood, the Merlin packs an AK4493 DAC chip, a Minaro 768 USB module, and a clean op-amp analog stage. This combination promises high-fidelity audio reproduction, even at its surprisingly affordable price point. During testing, the DAC performed exceptionally well, delivering a clean and undistorted signal, as expected.

One notable aspect is the Merlin's apparent design philosophy: letting the connected amplifier (in this case, the Gremlin) handle much of the tonal shaping and distortion. This approach results in a surprisingly neutral and pure signal from the DAC itself, maximizing compatibility with various amplification systems.

Features and Connectivity

The Merlin DAC offers a straightforward set of features, with USB-C input and both XLR and RCA outputs. While this simplicity keeps the price low, it also means some common features are absent, including Bluetooth, a remote control, filter options, and coaxial input. The lack of a 4.4mm output is a notable omission, considering the Gremlin amplifier uses this connection type for balanced audio.

The Gremlin Amplifier and Stacking Options

The Merlin DAC is particularly well-suited for use with the Apos & Geshelli Gremlin tube amplifier. This combination creates a balanced audio system at a relatively low price point compared to other balanced setups. The Merlin's clean output complements the Gremlin's characteristic tube sound and distortion.

Sound Quality and Listening Experience

The combined sound of the Merlin DAC and Gremlin amplifier is rich, warm, and lush. This combination leans heavily on the tube amplifier's characteristics, resulting in a pleasingly full-bodied audio experience. The Merlin DAC plays a crucial role by providing a clean, neutral foundation that doesn't mask or color the amplifier’s tone.

This system excels at conveying detail and creating a wide soundstage, making it suitable for various music genres. While not the cleanest sound profile, the warmth and saturation add to the overall listening experience, making it quite enjoyable.

Conclusion: Is the Apos & Geshelli Merlin DAC Worth It?

The Apos & Geshelli Merlin DAC is a compelling option for budget-conscious audiophiles seeking a balanced setup. Its affordable price, coupled with its excellent performance and compatibility with the Gremlin amplifier, make it a strong contender in its category. While it lacks some features found in higher-priced DACs, its clean output and exceptional value proposition justify its consideration.

However, its limited feature set and reliance on XLR connections might deter some users. The additional cost of XLR cables and the optional stacking component further increase the total system cost. Ultimately, the Merlin excels as a clean, balanced solution for its price, particularly when paired with the Gremlin amplifier. It's a great choice if you prioritize sound quality and a warm, balanced tone, but not if you need a wide range of features.
