Cost aside, can anyone give me a compelling reason to "upgrade" from an RX-A3080 (which I use as a preamp) to the CX-A5200? One of the reasons I''d prefer the 5200 is not having the power consumption overhead of the internal amps of an AVR vs a dedicated pre-pro, assuming that the 3080 itself does not shut off the internal amps when an outboard amp is used (I'm not sure if this is the case or not).\n\nI'm not as critical with music as I once was, but that said the 3080 sounds EXCELLENT to my ears in terms of overall sound quality with both music and movies. However, I swear every time I fire up the 3080, I always think about the unnecessary power consumpton of the internal amps, to the point that it's probably chronic, and moreso when I'm listening to 2-channel music since I have a dedicated 2-channel amp for the mains. I realize this might be a silly reason to upgrade, but either way I've always preferred a dedicated processor anyway. But if there's a noticeable difference in audio quality between the 3080 as a preamp and the 5200, then that'd definitely push me toward the 5200.\n\nThoughts?\n\nMost likely splitting hairs. The 5100\/200 has the better specs but whether your ears can discern the difference is impossible to tell. \n\nThe main reason for me would be longevity. I use a denon x3500 for a preamp on my 2 ch setup, and have zero complaints.
