Are upgraded power cables really worth the money?


My system consists of musical fidelity a5 integraded and cd player, b&w 703 and a rel 305 sub. I'm Im using purist audio musaeus interconects and speaker cables. I understand and can certainly see how these cables have helped my system, but am a bit aprehensive about investing in upgraded mains cables. Do they really make much difference? With the system I have what would be the right amount to spend on them. Any suggestions?

Tvad's advice is excellent. Try one, if YOU can't hear A difference move it to another component and see if you can hear A difference. If after moving it to all your components you will have determined which components may be affected by a change in A power cord and will be able to focus on the specific cord you want to use on it. Not all (if any by some folks opinion) components will reveal a difference in PC's, nor all ears. If you can't hear a difference think of all the money you will save! :-)
Yes, power cords can make a positive difference. Is it a huge difference - no, it is subtle. Make sure your room is properly tuned and your speakers set up properly before you spend money on subtle tweaks like power cords.

If you have not treated the room yet, take your power cord money and spend it there first, you will get a MUCH bigger return on your investment...

Of all the upgrades and tweeks I have tried over the years absolutely nothing gave me more of a positive immediate differance than good power cords . I am currently using (3new) Virtual Dynamics Power 1,s on all my gear and I bought a used Nite power cord by Virtual dynamics for the power supply to my Tri Vista 300 integrated . For 1200 dollars total and the level of detail , black background and exceptionaly deep controlled musical bass with unreal vocals I would not be able to obtain upgrading any component for this price and have this quality of sound through my whole system be it analogue or digital . I was one of those very skeptical people till I heard the results . Like any product I,m sure there is a diminishing return to price ratio as some cords can be very very expensive but those lucky enough to afford them to get that last drop of juice out would say they are worth it . My cords would be conscidered mid to low priced and there is alot of excellant cables in this range that will give better results than upgrading equipment did for me in my experience. I suggest buying a used well reveiwed cable yourself and trying it out . Cheers
Agree with others here that you need to try them and hear for yourself as no one will convince you one way or the other; this hobby is just that way.

There are free trials avaiable from various manufacturers so I would suggest you partake and enjoy the experience.

tvad your advice sounds like my best bet. What would be an easily resalable cord to start with at a reasonable price?
