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.
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 a
sampling rate of 768 kHz.
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.
