I am about to upgrade from a Marantz SR82 Prologic receiver (still sounds good after all these years).
I have narrowed my search to 3 receivers within my budget. They are:
Denon 2105
Yamaha RX-V750
Marantz SR-5500
They all have similar features, but there are a few minor differences between them. I like to listen to a lot of music and watching movies/music DVDs, so the sound quality is important. I know they will all give good sound for the money. I also considered an Onkyo TXSR-602, but it was lacking a couple of things I wanted.
That's the background, so now to my question/s....
I've been trying to find power supply/consumption specs on all of these AVs and can't seem to find them for the Marantz and Yammie. The Onkyo (which I dismissed) uses 650W and the Denon uses 630W. What I am not sure about, is how this statistic affects the sound quality and the "headroom" at higher volume levels. Also, if power consumption for a given AV in its budget class is only, say 450W, does this mean that its power supply is more efficient in its use of power, or does it mean that it is just smaller and less robust? So would a power supply using 650W in an AV in the same budget class be able to supply more RMS power to all of its channels? Or does it just mean this is a less efficient supply and more costly to operate? How much importance should be attached to this when deciding between similar featured machines?
