The premium DAC with VOLTAiR technology.

Diamond is the ideal DAC and preamplifier for anyone who plays music exclusively from digital sources. Diamond offers connection options for six digital sources and an external word clock. The superior VOLTAiR technology, in combination with the premium DAC including DLP120, allows digital players to perform in new sonic dimensions. The analog volume control ensures high-resolution dynamics even at low volumes.

SOURCE OF JOY

Up to 6 (!) digital stereo sources can be connected to the Diamond.

Diamond offers one stereo USB and one AES input each, as well as two optical and two coaxial stereo inputs. Both PCM audio and DSD audio can be converted via USB. PCM audio is received in S/PDIF format via coaxial (RCA), optical (Toslink F06), and balanced (AES/EBU) inputs.

Source selection is performed using the selector switch on the front. The selected input is also shown on the dot-matrix LED display: USB, COA1, COA2, OPT1, OPT2, or AES. After approximately two seconds, the display shows the selected clock source as well as the detected sample rate.

ALWAYS IN SYNC

Diamond can do more than just synchronize to the clock integrated into the digital source signal.
As a specialist for digital players, Diamond offers a word clock input.
The source of the clock signal can be selected using the CLOCK switch.

Source = Diamond synchronizes to the digital clock in the source signal.
Word = Diamond synchronizes to the digital clock signal applied to the WORD IN.

WELL INFORMED

The DAC automatically adopts the sample rate and resolution of the digital playback source, regardless of whether a streamer, computer, CD player, or external word clock is connected. The detected sample rate and selected clock source are shown on the dot-matrix LED display. For example, U768 is an acronym for a clock signal in the USB stream with a sample rate of 768 kHz.

EVERYTHING UNDER CONTROL – OR PREFER SLAVE THRU?

Diamond has two stereo output pairs for connecting power amplifiers or active speakers. One output pair features XLR connectors, the other RCA. Both carry the same output signal, which is controlled in level by the volume knob on the front. Using DIP switches on the rear of the device, the volume control for both outputs can be individually bypassed. This allows, for example, a headphone amplifier with its own volume control to be connected to one of the outputs.

THE DAC768

The conversion chip used in the digital-to-analog converter is the highly acclaimed AKM AK4490 Velvet SoundTM premium DAC chip, which reproduces the finest sonic details thanks to its architecture. It converts PCM audio with a resolution of 32 bits and a sample rate of up to 768 kHz, which corresponds to 16 times CD resolution. Direct Stream Digital is also supported up to a resolution of DSD4 or DSD256. Unlike the DAC768xs, the DAC768 offers not only an AES/EBU digital input but also the SPL DLP120 with VOLTAiR technology.

THE DLP120 (DUAL LOW-PASS)

Every signal that is passed from a DAC chip into the analog world must be filtered by a low-pass filter. The DLP120 contains two of these: one for PCM and one for DSD audio signals, as different roll-off frequencies are required.

Unlike any other DACs in the world, our analog low-pass filters utilize SPL VOLTAiR technology, which provides increased dynamics, headroom, and sound quality.
