I believe you already have everything you need. You have an integrated amp - Rogue that has all analog inputs (no internal DAC). Your Yamaha CD/SACD player connects to the Rogue integrated amp via a pair of analog RCA interconnects.
Put an SACD in the Yamaha, hit play. Same as a CD.
Are you trying to improve the sound quality of the Yamaha CD/SACD player by adding an external DAC? Or do you just want to play SACDs with the equipment you already have?
