Replacing my Denon AVR2500 (Pro Logic only) as part of HT upgrade. Buying Sony KF42WE610 RPTV and Denon DVD1600. I've used the 2500 as a video switch. Wasn't a problem with non-progressive scan DVD and old non digital TV. Ideally would like to use the new AVR as a digital switch also. But, I'm running out of budget. Considering the Denon AVR1804 and AVR2803. Biggest concern is bandwidth listed on the component inputs. 1804 list 30MHz and 2803 lists 100MHz. -3dB bandwidth in both cases. Will either of these be sufficient for running HDTV and DVD signals through? Ideally I'd like to save the $300, but don't want to make a shortsighted decision. FWIW, the 2500 has done a wonderful job on audio with my Kef Q70 speakers. From numbers alone it appears either of these will perform similar (though I'll listen, of course).
