The possibility of adding the DAC-1 option to the REVO SC-2 makes it an even more universal and interesting device.
It is not just the addition of a digital input, but a proper complete DAC section, which technological refinement places it at the top of world production levels. It is indeed a very similar solution to the one mounted on REVO DAC-1 and DS-1, and on the brand new HS-DA1, from which differs only in the practical implementation, while functionality and performance are the same.
Plus, since it integrates the conversion section in the preamplifier, it eliminates the need for proper interconnection cables which, if high quality, could cost much more than the DAC option or even than an external DAC unit.
The DAC-1 board has a USB input which can work up to 192 KHZ, 4 SPDIF inputs, as well as optical coaxial and XLR inputs. The conversion section is handled by a pair of PCM1704, very high quality True PCM multibit converters.
