Unparalleled Audio Precision: A Short Review of the Diamond Premium DAC with VOLTAiR Technology.

The Diamond Premium DAC with VOLTAiR technology stands as a pinnacle in digital-to-analog conversion, offering an unparalleled audio experience for those who exclusively indulge in digital music sources. With connectivity for six digital sources and an external word clock, the Diamond sets itself apart with its superior VOLTAiR technology and premium DAC featuring the exceptional DLP120. This, coupled with an analog volume control, ensures the highest resolution at any volume level, delivering an unmatched analog feel and extraordinary soundstages.

One of the standout features of the Diamond is its versatility in accommodating various digital sources. Offering stereo USB and AES inputs, as well as two optical and coaxial stereo inputs, it supports both PCM and DSD audio conversion via USB. The source selection is intuitive, thanks to the front control and dot matrix LED display, which elegantly showcases the chosen input and, after a brief moment, the type of clock source and detected sampling rate.

The Diamond's synchronization capabilities are noteworthy, not only aligning with the integrated clock in the source signal but also providing a word clock input for digital players. The DAC seamlessly adjusts to the sampling rate and resolution of connected devices, be it a streamer, computer, CD player, or external word clock, ensuring a consistently high-quality audio output.

Equipped with two stereo output pairs – one with XLR and the other with RCA outputs – the Diamond offers flexibility in connecting power amplifiers or active loudspeakers. The volume control on the front panel governs both outputs, with the option to individually switch off the signal path for each output via the DIP switch on the device's rear, catering to various audio setups.

At the heart of the Diamond is the DAC768, featuring the acclaimed AKM AK4490 Velvet Sound™ premium DAC chip. Capable of handling PCM audio with a resolution of 32 bits and a sampling rate of up to 768 kHz, as well as DSD audio up to DSD256, the DAC768 ensures a meticulous reproduction of sound details. The integration of the SPL DLP120 with VOLTAiR technology in the DAC768 sets it apart from its counterparts, offering dynamic headroom and sound quality that exceeds conventional standards.

The VOLTAiR technology, operating at a DC voltage of 120 volts, is a testament to the Diamond's commitment to achieving the highest audio quality. The proprietary SPL 120V SUPRA operational amplifiers, designed to handle such high voltage, contribute to exceptional technical specifications and sonic benefits, including an impressive dynamic range, signal-to-noise ratio, and headroom. This technology, unique in the world, elevates the listening experience by delivering rich detail and a relaxed, immersive ambiance.

In conclusion, the Diamond Premium DAC with VOLTAiR technology stands as a masterpiece in the realm of digital audio conversion. Its meticulous design, advanced features, and commitment to sonic excellence make it a worthy investment for audiophiles seeking an unparalleled audio experience.
