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.
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.

See if you can find a used "Tice Audio Block" - Makes all the difference in the world to audio, especially if you live in an apartment building.
You´ll get definitely improvements!!!! Since you´re short of cash, try first cleaning all connections with electronic contact cleaner and Q tips or way better pipe cleaners. Make certain everything has been disconected for a while before doing this. If you can disconnect the energy for your wall plate and are hand skilled and feel confident in doing this!! if you doubt don´t try safety first...a cleaning of the cable contacts with plate and contact points with plug will improve . Do same with every component with detachable power cords cleaning contacts at both end and in component chasis, be aware of residual voltages!!!!, same for TV, etc. Do same for RCA plugs and cables in contact points you won´t regret it If still have some limited money ammount gor at least for a cheap Monster conditioner like HTS 800 which will do for 60-70 dollars. Also adding ferrite core filters from radio shack at 5-7 dollars at each power cord will lower RFI. So far all what I´ve done in current has paid big. Look for tweak in internet sites and if looking for improvement all around start playing with vibration control of components, give it a try..., even using a book to support your digital source will have effect on sound quality.... Good luck Good luck
