How to fight dirty power - I need your help

Q: "What is the best way to solve the problem?"

A: No such answer, except for having your own generator...

It takes several tools and approaches to tackle noise.

I would buy a used little ONEAC isolation transformer (2 amp) from eBay and plug your CDP to it. Then I'd plug the transformer to the Monster. I would get a Highwire Wirewrap and attach it to the power cord of your Monster. I learned this from Bluenose, who also has a Monster 2000. The Wirewrap will smoothen and ease the musical presentation by removing HF grunge. You can also get a second Wirewrap for your power amp.

Isolation transformers are cheap in eBay. You can get a large one (at least 4 times your power amp's RMS) to plug the amp to. Take this from someone who uses SIX transformers in his audio/2 channel HT plus a Tice A/V Solo. The biggest one is 3,000 W (220V in / 110 V out).

Another route is to buy a De Zorel line filter (www.dezorel.com). They are not power constricted unlike conventional designs and run for about $349 (entry level)to about $1200.

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.
