I think you may be misunderstanding the conversion process. SACD (or DVD-A) digital to analog processing is done in the player. The resulting analog signal is passed to the 950 via its 5.1 multi-channel analog inputs, bypassing (6-channel bypass!) any DSP processing. I understand you can do this A/D, D/A with your MC-12 to allow for some bass management, but it is not necessary. IMO, comparing Logic 7 to SACD is like comparing apples to oranges! Best wishes!
