Best 5.1 options under $5k

Build what you want. I am a 2ch guy for music and have 5.1 in our living room for family entertainment and lo level listening during parties.

SVS makes nice stuff as do Klipsch for a 5.1.

It will primarily be a surround sound setup but I don't want to neglect a great 2ch experience either as we will have a Pro-Ject turntable connected among others

I guess in a perfect world I'd be looking for a nice compromise of the two with a slight lean towards Home theater

I was thinking about checking out the Focal Chora 826 towers in addition to the previously mentioned SVS.  I've heard good things about the Klipsch RP-8000f as well and they're certainly within budget

Personally, if you are strictly 5.1 I would seek out the best front 3 you can find, the one that sounds best for music. Same with sub. Most everything translates well for movies. I no longer think surrounds have to be from same family, although if you can pull it off it can’t hurt. For example I used a B&W surround because it afforded easier mounting and fit my room better than anything else.  What gear is in front of said speakers?  That's a factor especially on the music side.  

I was thinking something like the Denon x3700 or 4700 but I have not decided on that yet.  At this time I am heavily leaning towards spending most of the budget in the front speakers and adding surrounds at some point in the future
