Well, first off you should tell us your budget because some of us have varying definitions of what breaking the bank could mean. If you want good performance for the price, check out what Onkyo and Yamaha offer in your price range. If you can spend about $600 you can probably land an Onkyo TX-SR806 which would give you plenty of features to use. If you can only go as high as say $400, then there are still some from both companies mentioned that can handle the lossless audio tracks from Blu-ray movies, but they have less features like no pre-outs, less inputs, smaller amps, etc.
Need help picking out the right receiver...I recently purchased the Sony bdp s550 BLU-RAY player. I'm currently running the audio through an optical cable to a older Sony es 5.1 Dolby digital/dts receiver that precedes hdmi and any multi-channel analog inputs.Now that I'm considering upgrading the receiver, what is the best receiver to capture all the lossless audio that the 550 is capable of (through its own onboard processors) without breaking my the bank??? Do I really need a receiver with more of the same processors? TKS. RON D.
