Cables like all other components are integral to any system and can affect the sound as much as buying any new electronic component. You will also benefit from a power conditioner especially if you do not have dedicated lines. What is suitable has to do with the rest of your system.
Will a Line Conditioner give better picture and sound?
I'm currently new to high end. I have been gathering better and better components over the last year now. But have ran out of cash. I was told that I should look in to better cable and a line conditioner until I can afford better components. But will a line conditioner really give me a better TV picture and better Audio sound. I would really thank any advise.
