In my opinion the only way to know if it's worth it is to have a home audition. No one can tell you what something is worth. I submit you should try room treatment or a power cord first.
If you are really looking for a serious answer as opposed to stirring the pot of contention, telling the community what your system is like and what cables you are using now will go a long way towards getting meaningful responses.
