SPL's Diamond – From Germany's pro-audio company SPL comes their new Diamond DAC [€2'500] whose RCA/XLR analog outputs can be individually set to fixed or variable via rear-panel dip switches. In variable mode they're preceded by a precision analog volume control. The company's Voltair circuitry runs its parts at ±60V to significantly reduce distortion. There's also an external master-clock input on BNC. For more, visit their website.
