Better check into a seriously good digital cable, too, or else you'll be potentially wasting your time with the DAC. On a very good system, the digital cable can have a large effect on how good the DAC sounds. As with any other part to a hi end system, the sky's the limit on such cables. I surely would not skimp on it, or else the end result of the DAC's performance may not be to your liking.
You also should determine if you want a SS DAC or tube DAC, depending on what you want improved from the sound of the Saturn.
