With the plethora of both standalone and built-in DAC’s into different electronics, we get asked the question of which “DAC is better” a lot. We also observed many discussions about how one could use a DAC to double up as a digital preamplifier to drive their amps, a topic we do have lots to say about but not for this writing.
One of our clients owns both a Gryphon Scorpio S and a Diablo 120. He was wondering whether the DAC in the Scorpio S is superior to the optional DAC module for the Diablo 120.
From a spec standpoint, the chip used in the DAC for the Diablo 120 is a better chip than the AKM used in the Scorpio S and we believe apples-to-apples, the former should perform better. However, we encourage listeners to try it on their own. Also, it depends on the cables and interconnects you are using.
Here’s what you do with your (a) and (b) test.
(a) Run the Scorpio S directly into the Diablo 120 from the XLR analog output.
(b) Run a digital 75 Ohm cable from the Scorpio S directly into the DAC module
