I am upgrading from my Sony soundbar

(no laughter please). After going through these forums and doing some research, here is what I came up with. I was looking to stay around $2500.00. Please feel free to critique and suggest changes as that is why I am posting. Thanks in advance.
Receiver - Marantz SR 5005
Mains - Polk RTi A5's
Center - Polk CSi A6
Surrounds - Polk FXi A6's
Sub - ED A2 - 300
