The SP-SB23W has both digital (SPDIF) and analogue (RCA) inputs. Understand that the best signal path from source is via the digital inputs as the internal DSP and DAC would take care if the stereo reproduction.
What about the RCA inputs? Curious if there's a double conversion going on with the analogue signal - seems a waste if it is so.
