I've got the Summertime Blues. Power conditioner necessary?

The cheapest and most well worn path is installing dedicated 20a lines to your system’s wpo’s using some higher quality 10 guage insulated wire back to ideally a dedicated subpanel with it’s own ground. So basically an isolated circuit from the rest of the house ...

If you're in the US, this is a violation of the NEC and it would be potentially dangerous anywhere. NEC requires all house grounds to be bonded together at the main service panel.

I guess the first point to make is I live in Australia, and our electical code is different to the US. Secondly, I was not inferring to run a seperate ground or ignore the US electrical code. I meant that the installed sub-panel would have it’s own ground, being the legally compliant and available ground in the house. Thirdly, I was only providing general advice from an audiophile’s perspective. I did not claim i’m an expert or licensed electrician, hence why I posted a link to a PS Audio article on the topic in my post. I trust that addresses all your concerns.

I agree that where possible, a dedicated line is the starting point. Because we must share ground with the main household system, noise can still infiltrate, but it can go a long way toward isolating the system AC from the anomalies of the rest of the house.
I installed a massive iso transformer system (10kVa) which has an additional ground that ties back to the main ground. Despite that shared ground, the system is dead quiet (i’m using extremely efficient horns, so you can hear any electrical gremlins).
Apartments are a whole other challenge as @melbguyone mentioned.

From your previous post,

"am looking into my electrical system (think I have a dedicated line)"

Did you have a dedicated line installed? Highly unlikely that you would just have one. A dedicated line with upgraded outlet does more than just help with noise issues. Seems like common sense to me that a dedicated line should be first before getting a power conditioner. Have encouraged many to have dedicated lines installed, and everyone was very pleased with the results saying it was well worth the cost.

Great thought on the post. I like the version from Blue Cheer a little better.
