Some people prefer an avr for their music only system, to me {setting the performance positives aside} just the basic stuff like...
aesthetics {I like the looks of stacked separate components},
simplicity{try to navigate around an avr's remote quickly lol, my dacs remote has 12 buttons most avrs will have 70+ which will have multiple functions and then multiple menus, that most need a tv screen to navigate...},
Longevity- you won't be needing to upgrade your 2ch rig for a long time, my father still uses one he bought in the 70's...
Stability and strength- my experience aside- avr's break especially when pushed, its common sense the more circuitry the more chance something is going to fail, plus the amp sections they jam into them things aren't normally sub 4 ohm stable if even 4 ohm unless you spend big dollars...
replacement- If you buy an $800 avr and the processor gets outdated or cooks you need an entire new unit, if you buy separates and you spill a coffee in your preamp {or dump a flower vase full of water into it, I've done it, actually unplugged it and put it in a ziplock bag with an eva dry and it still works} you just buy a new preamp, and chances are you can sell your water soaked one on ebay for a few bucks even broken...
Resale value-Try and sell a 5 year old AVR for 20% of what you paid vs selling a Preamp/amp set from 5 years ago will most likely get you 75% of your Investment back...
So I am sure I can come up with more, and AVRs have their place, they are the way to go with HT for sure, but music only IMO should be done with either a stereo receiver or pre and amps {ideally mono blocks}.. Sure avrs can have amps added to them, and you can use it with a tv later if you wanted to, but for music only, why bother...
As for the not likeing dac's, when used as a preamp I love them, I can tell the difference between the dac in my xda2 and the dac in my yamaha avr, its like night and day, and actual easy to distinguish which is better difference and that avr isn't a cheap model...
I don't mix music and HT, I have separate systems for each, if its not in your budget and you need 1 system that does it all, or thats the way you want it that is fine too and will make sound, but there is something simple and clean of a nice 2.2 system... or even simpler a 2.2, but I like a lot of bass, and since most towers are using an average driver in the 6.5" range, abundant low end is a thing of the past...
