the_lhc:Hemmy, you have a different amp and BDP compared to Jarra, so he can't really use your experience as a guide.
If you use HDMI you're using the amps DACs, if you use analogue connections you're using the BDPs DACs, which sounds better will depend very much on the relative quality of the DACs in each component.
As has been said, try both and chose the one you prefer.
+1 on that, and if you go down the multichannel analogue approach, the interconnects have a greater impact on the quality of the sound, as you no longer have lossless digital between the BDP and Amp.
