SPL-Diamond

The premium DAC with VOLTAiR technology.

Diamond is the ideal DAC and preamp for anyone who plays music exclusively from digital sources. Diamond offers connection options for six digital sources and an external word clock. The outstanding VOLTAiR technology, in combination with the premium DAC including DLP120, allows digital players to play in new sound 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 a stereo USB and AES input 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 in both coaxial (Cinch), optical (Toslink F06) and symmetrical (AES/EBU) format.

The source is selected using the selector switch on the front. The selected input is also shown in the dot matrix LED display: USB, COA1, COA2, OPT1, OPT2 or AES. After about two seconds, the selected clock source and the detected sampling rate are shown on the display.

Always in rhythm

Diamond can not only rely on the digitally leaked
Synchronize source signal with built-in clock.
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 itself to the digital clock present at WORD IN.

Well informed

The DAC automatically adopts the sample rate and resolution of the digital playback source. No matter whether a streamer, computer, CD player or an external word clock is connected. The detected sampling rate and the selected clock source is shown on the dot matrix LED display. For example, U768 is an acronym for a clock signal in the USB stream with a sampling rate of 768 kHz.

Everything settled - or rather Slave Thru?

Diamond has two stereo output pairs for connecting power amplifiers or active loudspeakers. One pair of outputs with XLR, the other with RCA outputs. Both have the same output signal, the level of which is controlled by the volume control on the front. The volume control for both outputs can be switched individually from the signal path using DIP switches on the rear of the device. For example, a headphone amplifier with its own volume control can be connected to one of the outputs.

The DAC768

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

The DLP120 (Dual Low Pass)

Any signal that is passed from a DAC chip into the analog world must be filtered through a low-pass filter. Two of these are installed in the DLP120: one for PCM and one for DSD audio signals, as different roll-off frequencies are required.

In contrast to all other DACs in the world, our analog low-pass filters use SPL VOLTAiR technology, which increases dynamics, headroom and sound.
