I presently have a denon dv2200 that i would like to upgrade.I also have tosh. HD player which is excellent.I'm looking into getting a better universal player that would be connected via component.I have alot of dvda/sacd and the denon just doesnt do it for me anymore.I dont know how the oppo would compare or the marantz vc6001,but would like some suggestions.Sound and video are important but more to the sound side.Basically whats out there that are steps above the denon dv2200.Budget would be 5-600.thanks
