Following is from a c/net review on the Pioneer universal player:
"The 563A's rear end sports a full complement of the essential jacks: component, composite, and S-Video outputs, coaxial and optical digital audio connectors, and the 5.1 analog audio outputs.
To hear SACD and DVD-A surround sounds, make sure your receiver has 5.1/multichannel analog inputs--the 563A's digital audio connectors are for CD/Dolby/DTS signals only. The owner's manual isn't terribly clear on this point, but trust us, don't buy a 563A (or any SACD/DVD-A player) unless your receiver is equipped with 5.1 analog connections."

I have Polk speakers, they are not bright and will not sound as good as high end Paradigm or mid end B&W, but certainly not lacking in high frequency response.
