TV power cords; Money well spent, or money wasted?

Swapping out the cord will in no way harm the set. On my Panasonic panel, I can see an improvement in image smoothness when using an upgraded cord- nothing fancy- just a more robust cord. Even my wife sees it, so I left it in.

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.

My Sony XBR flat panel didn't come with any rabbit ears or 99¢loop antenna to modify.Maybe its time for them to upgrade the warranty info.

Wasted, unless the cord is defective.

I also have a Sony "Z" series LCD. I have tried several upgraded power cords and have noticed very minor improvements such as slightly enhanced detail and slightly improved color brightness and richness. The improvement is so slight, I would not spend much money on another cord for this purpose. Where I spent money and noticed a significant improvement was on my HDMI cable. I purchased 2 Wegrzyn Silver HDMI's and was very pleased. Sharper, brighter image with much improved color and detail. Since the HDMI also carries the audio signal, I was greatly surprised and happy that there too was a significant improvement. I have them hooked to my satellite receiver and Blu-ray player. I was previously using Monoprice HDMI's which are certainly a steal for the $ and definitely no slouch but the Wegrzyn is surprisingly better.

Believe me, the HDMI would be the better choice to spend the money but if you have an inexpensive aftermarket power cord laying around, use it too.

Happy listening (and viewing).....
