I have an interesting dilemma! I'm planning on upgrading my current AV Receiver, Yamaha RX-V450 to a more powerful unit and in the same price range I can go for either a Yamaha RX-V650, Marantz SR550 or Cambridge Audio 540R.
Each one has its own unique sound and to be honest I like all of them. Maybe I would have a problem with the Yamaha as with my current unit, I feel it is underpowered and does not really produce 85w RMS per channel as specified.
