Which powerfilter for best picture on Plasma & LCD

Changed the PC on my Pioneer Plasma and it did make a difference. Not a huge difference but a enough of a visual difference.

Richard Grey component may meet your video power filter needs for Sony HD TV.

No aftermarket power cord will plug directly into the back of your Sony. You will need an adaptor (Audio Advisor)
I have a Sony XBR Bravia and use a spare Shunyata Alpha power cord into Richard Gray AC filter with very good results. Takes away any trace of haze. 3D ish sometimes.
Once you get the adaptor you should see a difference with any better cord. Dont forget to change the wall socket,(from Shunyata, found here on Agon also)

I put a Maestro outlet in my cheap monster cable hts3000 power conditioner and I'm just amazed at the picture I'm getting with Directv HD 1080i signal!.. My Pioneer krp-500m plasma looks very sharp and the colors look so natural and life-like...skin tones look accurate and life-like too. The whole picture looks so crystal clear and so life-like that it looks like I can reach out and touch someone!.. I've only had the maestro outlet in my power conditioner for about 15 days and the picture might improve even more as the outlet settles-in more in the next week or two. I watched a few reruns of football games and they looked.. DAMN GOOD ! Look at my review

If your able to, I suggest upgrading your VAC to a dedicated 20 amp circuit using 10 -12 ga. copper wire in metal clad conduit terminated with, at the very least, a hospital grade isolated ground receptacle. If the VAC from the street to your breaker box is clean It's not uncommon for some conditioners to degrade the VAC after this upgrade. Cost for a licensed electrician, $150-$400.
