The DAC2X supports up to 24-bit/192kHz resolution on all of its PCM inputs, including USB. Since it can receive a DSD-encoded bitstream via USB, it can also be used to play DSD files. It can be used to play SACDs from any EMM Labs SACD transport via the company’s proprietary Optilink digital optical interface. Moreover, the DAC2X upsamples all digital audio to 5.6MHz DSD, which is twice the sampling rate of SACD. Supported digital input formats are AES/EBU, S/PDIF, USB, and Optilink.

At a time when some DACs are no larger or heavier than a USB stick, the DAC2X has a precision-machined aluminum chassis measuring 17"W x 3.6"H x 15.6"D and weighing 26.4 pounds. Except on its rear, where the presence of connectors helps to limit resonances, the chassis walls are 0.25" thick. The relatively unadorned front panel announces the DAC2X’s limited functionality, and thus its seriousness of purpose. There’s nothing here that’s not strictly related to a single mission: the conversion of digital signals to analog. This means that the DAC2X’s front panel does not have a volume control. What it does have are a standby/power-save button and several LED clock-control indicators. Another LED lets you know that the DAC2X has detected a valid signal at the selected digital input. Two other LEDs display the sampling frequency.

The front panel’s remaining buttons are for polarity inversion, mute, and digital input selection. There is also a mysterious Alt button, to be used for some future, as yet unspecified function.
On the rear panel are a main power switch, a female IEC power connector, input connectors for the digital inputs, and stereo analog line output connectors (fully differential balanced XLR and single-ended RCA). Four S/PDIF inputs are provided: two each for coaxial and TosLink. There are also two USB inputs: a high-speed Class 2 for audio signals, and one for software and firmware updates.

The DAC2X subjects a digital signal to a number of proprietary technologies, many of them developed for EMM’s flagship XDS1 SACD/CD player. To start, EMM states that the DAC2X’s proprietary high-speed, asynchronous Meitner Frequency Acquisition System (MFAST) circuitry captures the data almost instantaneously as it is presented by the source. Unlike phase-locked loop (PLL) circuits, therefore, MFAST is able to use the DAC2X’s internal clock rather than the source component’s clock, which typically has a high level of jitter.

Once captured by the DAC2X, the signal, whether DSD or PCM, is automatically upsampled to 5.6MHz and filtered by a Meitner Digital Audio Translator (MDAT) algorithm. This constantly examines the signal, and almost instantly adapts to any changes in the transients. EMM states that, because the MDAT filter doesn’t provide a fixed response, there are none of the pre- or post-ringing artifacts that typically manifest as spurious “rings” before and after a sharp transient.

The DAC2X also contains large, very expensive, proprietary, aerospace-grade composite-laminate PCB boards. These multilayer boards have a low dielectric constant, and spread heat evenly and obstruct resonances. According to EMM, they come very close to the performance obtained with point-to-point wiring, which is difficult or impossible to use in digital circuits. Unlike tube-based analog circuits, for instance, which might have fewer than 100 connection points, digital circuits can have tens of thousands of such points.

On the DAC2X’s analog board are its 1-bit, sigma-delta, fully balanced, differential MDAC conversion modules. These modules are not the off-the-shelf integrated chips used in virtually all other DACs, but are hand-built by EMM Labs using individual transistors, resistors, and capacitors.

Also on the analog board is the DAC2X’s master clock. This circuit produces less than 1 picosecond of jitter. Unlike in most other DACs, whose clocks are located in the digital circuitry, the DAC2X’s clock is placed next to the DAC modules. This keeps the clock’s circuit paths very short, thereby, per EMM, further reducing jitter and other waveform distortions.

The DAC modules and clock are protected by grounded metal covers that isolate these critical parts from the rest of the circuitry. Under the DAC2X’s top cover lies what EMM calls a Charge Management Plate. Consisting of a group of copper dots arranged above the ground plane, this is designed to, when charged, stabilize the electrical field around the DAC2X’s audio circuits. According to EMM, it provides an environment not unlike that found inside vacuum tubes, which have extremely stable electrical field gradients due to their high supply voltages.

Finally, EMM states that the DAC2X’s proprietary, highly isolated X Power System v3.1 power supply synchronizes its operating frequency (or resonant mode) to that of every other electrical system on the chassis, thereby almost completely eliminating noise. EMM says that its extremely green power-delivery system outperforms typical switch-mode and linear power supplies.

Speaking of power, the DAC2X comes with a power cord made for EMM Labs by Kimber Kable. While this cord is not Kimber’s top model, it’s a big step up from the molded cords that accompany most components. While it’s not something I would ultimately mate with the DAC2X, its inclusion is a nice gesture.

The DAC2X is operated via its front panel, its own infrared remote control, or RS232 transmission. The remote is elegant and impressive. Resembling the controls included with many Bryston models, it’s precision-machined from a solid block of aluminum; it’s heavy and feels indestructible.

The DAC2X’s five-year warranty covers parts and labor. At a time when many high-end manufacturers provide warranties of only one to three years, EMM Labs deserves props for doing the right thing.
