Neutron,
Smart choice to use the PSA Quintet. Both your audio and video performance should be improved. Since your TV is connected to the Quintet, you should be able to see an improvement in video quality with the use of a GOOD power cord. One suggestion is the Harmonic Tech Pro AC-11. It is well worth the price especially in the used market.
By the way, put your amp thru the Quintet as well, on its own zone. The performance of your amp will improve.
Enjoy.
