I am considering getting the HD621 and would desire to get the new HD audio codecs into my 861V4. I currently own a Pioneer BDP-95 which doesn't decode DTS-MA in the player so I am cosidering getting a new player. My question is -- is there a difference in the internal decoding capability of high end vs. lower cost Bluray players. I am considering waiting for the new Pioneer Elite model 23 or should I look at the BDP-05 OR is the BDP-09 a better player. My thoughts are that over HDMI it will not matter. Any thoughts would be appreciated.
