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 with the unequalled DLP120 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.
Reviews
“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.”
Hifistatement
Klaus Schrätz
“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.”

“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.”

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.
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.
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 asampling rate of 768 kHz.

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.
The new DAC revision can be recognized by the “DAC768v2” label on the serial number sticker.
The design of the DAC768v2 is unfortunately not compatible with devices that were built with DAC768.
In addition to the original DAC chip (previously AK4490, now AK4493), other components in the digital environment that are no longer available, such as the previously used version of the Spartan-6 FPGA (now Spartan-7), had to be updated. As the technical characteristics of these components are different from those of their predecessors, further technical adjustments had to be made to the device in order to achieve the best possible sonic performance of which SPL is known for. The analog low-pass filter with 120V technology is also different in the devices with DAC768v2.
It is therefore not possible to simply replace the DAC768 module with the DAC768v2 module.

The VOLTAiR Technology
The 120V technology is our reference technology. The 120V technology is unique in the world. It operates at a DC voltage of 120 volts. This is four times that of IC-based semiconductor op-amps. In our Professional Fidelity series, we refer to this unsurpassed technology as VOLTAiR technology.
The highest possible audio quality requires the highest possible audio operating voltage.
The 120V technology works with +/-60 V. To be able to handle such a high voltage, we have developed special proprietary operational amplifiers that can operate with a DC voltage of +/-60 V: the SPL 120V SUPRA operational amplifiers. This high voltage would destroy conventional components and operational amplifiers.
The 120V technology achieves exceptional technical specifications and sonic benefits. Technically, in terms of dynamic range, signal-to-noise ratio and headroom. Sonically, in terms of richness of detail and an absolutely relaxed listening experience.
By the way, the “120V” in the name of the technology has nothing to do with the local mains voltage from the mains power socket. This is about the operating voltage inside the device with which the audio signals are processed.
The mains voltage from the mains power socket is transformed to the required secondary voltage in the device’s internal linear power supply with toroidal transformer. Rectifiers convert this AC voltage into DC voltage required in the audio device.
Sounds good
With all devices of the Professional Fidelity series we develop not only according to plan, but also by ear. Many important components are installed on the circuit boards using Through-hole technology. This way we can ensure that we can use the best sounding components.
Home is where the heart is
That’s why we manufacture all devices in our own production facility in Niederkrüchten on the Lower Rhine, Germany.
