I have owned an SA-1 since that model was brand new. To play both SACD and CD disks, you will need to use the analog outputs. SACD information does not come out of the balanced or unbalanced digital outputs. The balanced analog outputs are the best sounding, but since your receiver probably does not have balanced inputs, stick with the RCA analog outputs. While the Arcam is a good-sounding receiver, I think that keeping the signal analog after the SA-1's processing is the way to go in your two-channel system. The SA-1 has truly excellent analog stages.
