Best 5.1 complete system under $3000

I want to buy a 5.1 system for under $3000 and need help.  I need everything as I am starting from scratch so everything has to be included in the price.  I will use it for both music and TV.  My favorite music that I love to listen too would be yanni's live concerts. I believe there is nothing like it.  Any suggestions would be very helpful.  I wish I could just go somewhere and listen but the only places around here have expensive systems.  Any help would be appreciated.  Currently I have Sony soundbar 5.1 system their top of the line which is good but it is a soundbar and I want better.  Help me out if you can.  Thank you.
BTW never built a home system and it's been 20 years since my last car stereo build.
