If I install '20A dedicated circuit'

Tvad, nice explanation.

Eandylee, it absolutely will help but there's always the qualifiers.

I don't know where anybody might get the notion that dirty AC coming from the street is somehow magically cleaned up if one splits the AC off into dedicated circuits/lines.

Everybody has dirty AC (some worse than others) and depending on the quality of components, everybody can benefit sonically from 'proper' line conditioning. In other words, the more resolving a system is, the more it will benefit from 'proper' line conditioning.

Dirty AC split off into dedicated circuits/lines simply means that the AC noise is now dedicated to that circuit/line.

Perhaps some people confuse dedicated lines with clean AC with the fact that in-house generated AC noise from dimmers, microwaves, appliances, etc. can be minimized by installing dedicated circuits/lines preferably on the opposing phase/leg in the service panel of where the majority of dimmers and appliances reside.

But again, dedicated circuits/lines does absolutely nothing to clean up the dirty AC coming in from the street and it certainly does nothing to clean up the bi-directional digital noise generated from a cdp/dac which will contaminate the AC all the way back to the service panel and out again into all circuits/lines.

Hence, one more qualifier for 'proper' line conditioning is that the line conditioner should be capable of bi-directional noise filtering.

-IMO

Stehno et. al.

It is my opinion that people do sometimes confuse dedicated lines with mains conditioning and that somehow a dedicated line will clean up the incoming AC. Another method that I happened upon is the use of isolation transformers per the attached web site http://www.audio-consulting.ch/. I have no affiliation with the company and do not currently use this method of mains conditioning. I have considered it, however, since my experience with passive conditioning was not positive.

Thanks, Chuck

I would think that a dedicated line is used to isolate your components from the rest of the items in your environment ie, dimmers, microwave, digitals, electrical motors etc. Given this, wouldn't it be advisable to further isolate the 'dedicated' lines by using a seperate ground system as well ? And then to keep one dedicated line for analog components and a second dedicated line for digital . Although none of this would 'clean' the incoming power it would, however, keep it from being contaminated further .
Just my thoughts, YMMV.
