Hello, i curently owe sony receiver 1200es, and about two months ago i bought player bd 550. Because receiver doesn't have hd decoding build in im using players onboard decoders, conected via 8 quinex qed q1 interconects. Im only wondering, if im experiencing same HD surround quality, as i would if i had say, sony2400es and used amp decoder and hdmi connections.Would be there any difference between those two receivers,in the sound quality? then i have pioneer dv 668s whitch i used like a sacd/ cd player, but now i have nowhere to connect it, if i want 5.1 sacd sound. Changin receiver to 2400es,would solved my connection problem, would it improve sound quality as well, or its just a waist of money? Speakers are kef kht1005, and projector sony vpl aw15. Thank you!
