Thoughts on using Sony PS3? rare 60gb SACD version

I'm wondering what your thoughts are on using the PS3 as the main audio and blu-ray video drive. It sounds good now, so I see no real reason why I should invest in a SACD player too, especially considering that the PS3 that I own is one of the most sought-after versions because it includes the best guts (which Sony later deemed too costly to continue packaging): the original PS2 'EmotionEngine' as well as the ability to play SACDs and DVD-Audio. I've used both and it does sound wonderful, even on my junk that is soon to be upgraded.

The answer always seems to be 'separates are better' but I see no reason why a digital signal going straight to a receiver/processor would need a separate component in this particular case.

Thoughts?
