There may be some general answers to Denon vs. Yamaha that may help me. General Comparison Questions: Specifically I am looking at the Denon 1802 and the NEW Yamaha 5550/5560 (These appear too new to have any reviews and I am sure few owners yet). Based on your past experience how well does the Denon amplifiers (1802 80W/ch) compare to the Yamaha amplifiers (75W/ch)? Is Denon or Yamaha a better match for my JBL N26 and N-center speakers? I apparently tend to like a "bright" sound that is crisp for music and dialog. DSP of the Yamaha seems quite different in description between the Yamaha and the Denon. I read the manuals and the Yamaha has the typical DSP's like Jazz etc but it appears to have this 21 program with 41 variation DSP capability. How does the DSP of the Denon systems typically compare to the Yamaha based on your past experience? General questions: What is the difference between DTS ES Matrix 6.1 vs DTS ES Discrete 6.1? I am assuming that the difference is the Matrix has a phantom rear center channnel and the discrete had a dedicated "real" center output. Is this correct? I have seen DTS but what is DTS ES? The Denon 1802 is $499 Crutchfield The Yamaha 5550 is $399 Crutchfield The Yamaha 5560 is $499 Crutchfield Thanks ALL!!!
