Diamond

Premium DAC with VOLTAiR technology.

Diamond is the perfect DAC and preamplifier for everyone who plays music exclusively from digital sources. Diamond offers connectivity for six digital sources and an external word clock. The superior VOLTAiR technology and the premium DAC combined with an analog volume control allowing for highest resolution at any volume makes the Diamond an one-of-a-kind DA converter that delivers finest soundstages with an unrivalled analog feel.

Everything under control

The volume is adjusted with a solid, milled aluminum, rotary knob. The Alps RK27 “Big Blue” potentiometer gives a pleasant “spoon in the honey” rotary feel.

“Richness of sound, flawless performance and dynamics are also included – together with a features set that should leave hardly any wishes unfulfilled: an almost irresistible offer.”

Source of joy

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

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

The source selection is done via the selection control on the front. The selected input is also shown in the dot matrix LED display: USB, COA1, COA2, OPT1, OPT2 or AES.

After approximately two seconds, the display shows the type of clock source and the detected sampling rate.

“Diamond scores with HiRes capability up to PCM 768 and DSD256. Thanks to its VOLTAiR technology, it operates with extremely low noise and distortion as well as rich in dynamics and with high resolution.”

Always in time

Diamond can not only synchronize to the clock integrated in the digitally fed source signal.
As a specialist for digital players Diamond offers a word clock input. The source of the
clock signal can be selected via the CLOCK switch.

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

Well informed

The DAC automatically picks up the sampling rate and resolution of the digital playback source. No matter if a streamer, computer, CD player or an external word clock is connected.

The detected sampling rate and the selected clock source are shown in 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.

“Music lovers who exclusively use digital sources and are looking for a DAC/preamplifier that is as easy-to-use as it is versatile and, above all, has a powerful sound, have come to exactly the right place with the new SPL Diamond.”

All variable – or Slave Thru

Diamond provides 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, which is controlled by the volume control on the front panel.

The volume control for both outputs can be individually switched out of the signal path via DIP switch on the back of the device. For example, a headphone amplifier with its own volume control can be connected to one of the outputs.

DAC768v2 – the SPL reference DAC in the newest revision!

The highly acclaimed AKM AK4493 SEQ VELVETSOUNDTM premium DAC chip is used as the converter chip in the digital/analog converter within the latest version of the SPL DAC “DAC768v2”, which thanks to its architecture reproduces the finest sound details. It impresses with even lower distortion characteristics and a wider dynamic range than its predecessor.

It converts PCM audio with a resolution of 32 bits and a sampling rate of up to 768 kHz, which is equivalent to 16 times CD resolution. Direct Stream Digital is also supported up to a resolution of DSD4 or DSD256. The DAC768v2 features the newest version of the Spartan FPGA – Spartan 7. In contrast to the smaller SPL DAC “DAC768xs”, it not only offers an AES/EBU digital input, but also the new, optimized SPL SLP120 with VOLTAiR technology.

The SLP120 (Super Low-Pass)

The analog output of the DAC chip must be filtered by a low pass filter. In contrast to all other DACs in the world, the low pass filters here are built using VOLTAiR technology, which provides a plus in dynamics and headroom and sound. The filter specially optimized for the new SPL DAC768v2 is called SLP120 (Super Low-Pass).

The DAC768v2 inside the Diamond is equipped with the SLP120 – an analog “Super Low-Pass” filter with VOLTAiR technology.

DAC768v2 – what's new:

1. AK 4493 SEQ

The DAC768v2 is equipped with the latest generation of the premium DAC chip – the AK 4493 SEQ – from  Asahi Kasei (previously AK 4490).

The AK 4493 SEQ not only supports the playback of PCM signals at up to 768 kHz and DSD signals up to  DSD512 – this 32-bit stereo DAC with “VELVETSOUND™ technology” impresses with even  lower distortion characteristics and a wider dynamic range than its predecessor.

2. Spartan 7

The DAC768v2 features the newest version of the Spartan FPGA – Spartan 7 (previously Spartan 6).

3. The newest generation of the SPL low-pass filter “SLP120”

The DAC768v2 comes with a completely new tuned low-pass filter, which perfectly matches the sonic  strengths of the new converter chip. It ofers an even better representation of the stereo image as well as a  three-dimensionality we never experienced from any other DAC before.
