I know many variables come into play when comparing but all that aside I would like your opinions. Marantz SR-6300 (can't find decent info on this one) Denon 1803 Yamaha RXV1300 Onkyo TX-SR600 What I'm looking for is component switching (can somebody confirm this feature on the Marantz?), DTS-ES Discrete, DPLII, DD-EX. I'm pretty sure these models all have what I'm looking for in my price range. My usage would be 60% movies and 40% music. I'll need it to power some Energy Connisseur series speakers. Thanks in advance all!
