Will power conditioning really help?

Wow thanks for the replies.

BigJoe- I actually do not know what kind of sound/problem occur in relation to power.

Only real reason I am considering this is mainly due to the building I live in. It's 95 years old in the bronx, NYC. Always have had power issue, surges etc. I mean the breaker that serves my room also serves 5 outlets and 4 light switches. The wires are so old that they have fabric insulation instead of what you see in normal BX cable. All this must compromise something no.

Also the fact that I connect both my computer system/audio t.v must have an effect on the sound I am hearing no? I am pretty much in the same boat as Clio09.

I don't plan to buy one anytime soon especially considering the good ones cost 700+. If there were some in the 200 dollar range that would do anything I would consider it. What I do plan to do is finish modding my SB2 and getting a better power supply and upgrading my amp pretty soon. I hear to much background hiss in my music. Don't know if this is related to the amp or source. Thanks guys.

Yes $200 can do something even brand new. For $200 you can buy two Blue Circle BC86Mk3 power pillows. The Mk3 versions have double the filtering of the older models, so they are as good as four of the older power pillows.

Sorry for the sales pitch, but I happen to sell them simply because they work, period. Check other threads.

You can also contact Phil at Sonic Spirits who is your local Blue Circle dealer. Maybe he can let you demo a pair. For $300 can get you the basic BC606 Music Bar which is a power bar with the filtering of 2 of those power pillows.

I use a P300 on all of my front end components and I have had many friends come over and do the with and without test. Clearly it makes a huge improvement to have it in the system.

JW94055. Maybe so. But the power supply components in a piece of audio gear are not themselves passive and surely alter the ac significantly (changing it to dc if nothing else) and I believe that most of the power conditioner advocates ignore the function of real world power supplies. I do nothing whatsoever to the power coming into my pc and I can see no adverse effects from that policy. (I never worked for a power company, so you've got me there in terms of real world experience).

Tarsando. Thank you for your respectful response. There are far too many immature exchanges on the internet. Daimbert, please look into an inexpensive power conditioner line,
Tripplite. You won't be able to brag to your audio friends and some may even snicker, but the cost/benefit ratio is fine indeed.
