I have good power cables on all of my electronics and it makes a difference
@funkbass4 Few years back I put a better cables on my Sony TV - I didn't really notice any difference, but when my wife came home she asked "what have you done to the TV?" - I asked WHY? she said the colours were much richer and the contrast was better
I've since recommended it to friends and they agree the contrast is the biggest improvement - improved details in the darker areas, and on some TV's the colours do get brighter
I would look at Zavfino cables - if the device oyu has is two pin - you can get an adapter - they work very well
Hope that Helps - Steve
