SPL Diamond (Black)

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.

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.

For example W192 = External word clock signal with sampling rate of 192 kHz

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.

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 the RCA outputs can be 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.
