Ok guys, I have a pioneer 504hde with a pio 812 av amp & just about to replace my pion 656a dvd player with an 868 to make the most of my 504(hdmi). Now the question is should I really replace the 812 with the ax5i, to make the most of the 868, use ilink etc... Is the ax5i gonna sound that much better than the 812? Would like to make the most of my setup, dont want one particular pce to handicap the full system potential if u know what i mean?? Opinions please gents? Thx Mike.
