Technically not impossible, but convoluted -- you could get one of the Sony home theater systems with SACD capabilities, digital inputs, and pre outs, and then you'd have it. But it'd be really entry level, and all-in-one systems need to be well ventilated or they are prone to overheat. Not the best of choices.
What I do is, just get a good universal player. I have a separate system for computer listening, but that's not a requirement -- you could just switch the cables.
