I'm looking to upgrade my Yamaha rx-v596 receiver to possibly the Marantz sr-8200. I have Paradigm Monitor 7 mains, cc-370 center, and mini monitor surrounds with a PDR-10 sub. I know the store has these in their showroom, but they do not carry the yamaha receiver anymore. I am planning to bring in my yamaha receiver to do a direct comparison againt the Marantz and any other receivers in the sub $1500 range. The main reason for me to upgrade the receiver is to get one that is more musical and much less bright. I am assuming that in 2 channel music with a well recorded source should be like night and day when comparing the two receivers sound quality (Yamaha 2 channel/Marantz 2 channel source direct). The upper bass quality was lacking in the yamaha, especially in the center channel in 5 channel DTS music so I will be testing for this too. Other than the brightness/musicality, what else should I be checking for in the sound? I will be listening to about 50% music(Classic rock and classical orchestral) / 50% movies. Any recommendations for music/DVDs to bring for the tests? I plan to bring at least one powerful and one quiet orchestral piece, one rock song with good bass guitar, and one popular acoustical, natural sounding song. I assume if the music sounds good to me the movies should too. Any other reccomendations for a musical sounding, high quality receiver with all the bells and whistles (PLII, DTS-ES, etc)?
