I was at my local stereo shop last Saturday to see if they had the new line of Onkyo receivers. I wanted to see if they had the Onkyo TX-SR507 in stock but the salesman told me they didn't plan to stock the 507s until they got rid of there 506s. The price was right, $399.00 and I'm sure I could talk him down a bit more since I was thinking of also buying a blu-ray player. I did my research and the 506 just lacks the ability to decode HD audio but otherwise was a decent receiver. I was planning of also purchase a Blu-Ray player that can decode Dolby TrueHD and DTS-HD Master Audio so if the Blu-Ray player was doing the decoding would it make a difference if my AV Receiver didn't as long as it has HDMI inputs?
