I have the above plus Sky HD, PS3, Panasonic TH42PX600B TV and Q Acoustics 1010i's. I am really pleased with the results i get from my system and currently run everything through HDMI (plus optical cable for the Sky HD for 5.1) My question is; I believe I should change my connectivity on the Denon in order to benefit from the SACD, therefore is the best set up component & analogue 5.1 or component & digital optical. Which of these will give me best performance from all formats, or is there an alternative set up?
