How to fight dirty power - I need your help

Is your meter reading true or avg (peak or rms) voltage. If you are reading peak, it will seem high. If you feel that your readings are correct, call your utility. 126V to 130V is rather high. They may be able to make a "tap" adjustment on the transformer. As for power conditioning, I swear buy "balanced power". Any conditioner that outputs 60V + 60V rather than 120V + N. It will drop your noise floor dramatically. I use a Cinepro20 (same as Furman) for my amps and a PS PP300 for the front end. Good luck, Bob D

Thank you all for your help.

Sugarbrie – Is the Blue Circle BC86 similar to AudioPrism QuietLine? I have four QuietLine plugged into my audio/video circuit. They seem help lower the noise floor.

Psychicanimal, To get start, I’ll get a small variable isolation transformer to connect my CDP and pre/switch box. This will help me to identify the main source of the problem also. Does the Wirewrap make a noticeable difference? Do you have their website.

Bob- I’m very interested in the balanced power you are talking about. However, I’m afraid I know little about it. Could you introduce some web sites carrying or discussing the products?

I would only plug the CDP to the Isolation transformer...it really needs to stay in solitary confinement.

The thing about the ONEAC brand is that they use a patented "virtual ground" which isolates your house's ground from that of the isolated components. A lot of noise in a system is transmitted via the building's ground. You can always get a variable output isolation transformer and plug it to a ONEAC. Your CDP will operate at the right voltage. I know Sedond is doing that with his infamous modded ART Di/O DAC. He runs it @ 100V in order to get the proper operating DC voltage.

The Higwire you can get from Music Direct mail order here in Chicago for $25 (www.amusicdirect.com).

There's articles and DIY projects on noise reduction and balanced power in Jon Risch's website:

Now, for the money you'll spend on a big balanced power...

I got a big 3000W ONEAC (220V in/110 V out) for less than $200. I take electricity at the 220V level and it provides full lightning protection and about a 20 dB noise reduction in the audio band. Not bad. Next in series is a Powertronix 900W isolation transformer to which my Tice A/V Solo line filter is plugged to (line components only). I have two isolation transformers in series plugged to the Tice's digital outlet. My DAC gets a C-Core trans with a two pronged plug. The C-Core is plugged to a 2 amp ONEAC. My amp is plugged to the big ONEAC and it's using a Highwire Wirewrap. TDK clamp on ferrite cores are used judiciously throughout the sytem (99 cents each).

Needless to say, my system sounds very very clean and musical...no grunge, no artifacts, just really beautiful music, especially on vinyl.

The BC86 is similar to the Quiet Lines, but the BC86 works a lot better. Yes, I have compared them directly. Not even close. I do find the Quiet Lines do a good job on video.

There is a lot of info on the web. Do a seach for "balanced power" on Yahoo or any other search engine. The most popular brands are Equi=Tech, Furman and Cinepro. Most of the regenerators (PS Audio power plants etc...) also have a balanced outputs. One odd note.....the National Electrical Code requires balanced power to have ground fault protection, due to both lines having potential to ground. Some conditioners have it, some don't.(?)
