new polk speakers but i need a reciver

[batmanfan2188]

This is the list of speakers i plan on getting from Amazon

Polk tsi300 2 fronts
Cs10 center
tsi100 2 rear speakers
Psw10 sub

But I want a receiver to go with them but don’t know what to get. My total for the speakers is a little over $800 I am willing to spend about $2000 with receiver but I will have to add 2 speakers and a sub if the receiver is 7.2 will take any and all advice. Thanks for all the help.
