Hi all Need to enlist your help choosing a new DVD player to go with my plasma screen (Pioneer 504) and connect to Pioneer AX5i receiver. I narrowed it down to the Pioneers 668i & 757i I understand the HDMI advantage of the 668i especially with my 504 plasma, and also know of the i-link feature of the 757i connected to my AX5i amp. I am not very technical and want to buy a descent player. Both are going for the same price circa £400 Naturally the 868i with both HDMI AND i-Link would be the natural choice to go with the 504 and Ax5i - BUT - It is twice the price of the other two, IS IT twice the performance!!!! Thanks for your help.
