You sacrifice so much with built ins, even the built ins that are very expensive and have the wall boxes dont tend to impress me... But for multi rooms it works, I have a bunch of them...
If its worth anything to you here is my advice for a system for $2000...
I recently went down this same road, and I listened to so many systems I was almost changing my mind about even upgrading... I am the type that wants the absolute best I can get for my money, so in HT I wanted a $3000 system that sounded like a $6000 system... And its tough to accomplish... But anyway, here is what I rec. for your budget...
Onkyo 709 $450
Onkyo TX-NR709 7.2-Channel 3-D Ready Network A/V Receiver | Accessories4less
HSU sub VTF2 $600
Ascend Acoustics 170se fronts, and 340se center, with 200se surrounds about $900 shipped
That is about $1950 but will sound really good, I own all the products {not the same exact emo amp but 4 others}
For in ceiling speakers I use Yamaha, search ebay for "yamaha ceiling speakers" there are some good bstock deals on there...
This will be the top of your budget but make one heck of a surround system... If you can strech it you can go dual 340s in the fron instead of the 170's which will cost about $150 more... But I use the 170se's in my office and they are amazing, very flat with real feeling mids, very well defined... Im listeneing to them rite now
IMO Ascend is the best value in speakers rite now, they sound so good they should cost much more.. The cabinets are vinyl covered so not the best there you can definetly tell where the money was spent making these speakers, its in the sound.... Not the appearance... But sound good, yes sir they do....
