Abe, can you please explain.

There might be some level of noise isolation between adjacent power outlets in a 'power conditioner' but they are rarely truly isolated. You'll get more isolation through separate transformer coupled conditioners or regenerators.
Thanks, I understand. So with an "isolated receptacle" on a power strip, there will be some bleed-thru to the next receptacle. Do you know how these receptacles are filtered?
For example; "Isolated filter banks"...

Do you know how these receptacles are filtered?
Varies by manufacturer but generally filters to reduce noise to adjacent receptacles and going back into the mains. But electrically, all the receptacle are still wired in parallel so there is never total isolation.
Thanks for the info, Abe.
I don't know why I said they were wired in series earlier, of course they are in parallel. I took Theory many years ago; it must be the meds I'm on.
The Line is fed to first duplex receptacle and then from the first wired to the second using the hot and neutral fed through terminals. From the second to the third and so on.

Actually, jea, what I meant was each receptacle would have it's own ground, such as in star-grounding. Also, each receptacle would have an isolated filter and not share filtering in the power strip.
I made a mistake in my post stating that the hot would be wired to each outlet in series.

lowrider75-
for over decade I have been using a Richard Gray Power Company(RGPC) Pro400.
I do not live in the grid (major U.S. city) so my power is relatively clean in comparison. These are outstanding products new or used. Excellent customer service by Dick and his crew at RGPC.
Very interesting, fantja.
I looked up reviews of the Richard Grey products. The RGPC 400 Pro seems like a similar design to the Brick Wall in that they both use an inductor and capacitors to filter incoming AC current. OTOH, the RGPC SubStation is an isolation unit which costs as much as a PS Audio Conditioner.The RGPC 400 Pro, however, uses "Balanced AC Surge Protection." Does anybody know what this terminology means?
They do not use the term "Balanced Power," of which I am familiar with.

the way it was explained to me;
the RGPC products uses/works in parallel w/ one's AC source. In my case, the local power company's transformer (for my particular street) sits on my property. I am very fortunate to live "at the source".
Yes, you could create your own "source" using the RGPC Substation. Watch eBay and buy it used/demo and save big bucks.
It is basic AC and CD circuit theory. Pull out your grade school science book or read the link below.
"The current in a series circuit goes through every component in the circuit. Therefore, all of the components in a series connection carry the same current. There is only one path in a series circuit in which the current can flow."
"If two or more components are connected in parallel they have the same potential difference (voltage) across their ends. The potential differences across the components are the same in magnitude, and they also have identical polarities. The same voltage is applicable to all circuit components connected in parallel. The total current is the sum of the currents through the individual components, in accordance with Kirchhoff's current law."
Simply put, if the AC receptacles were in series then each receptacle would have to be loaded or no current would flow, just like the old fashioned Christmas tree lights. Now, of course, the line voltage would have to be adjusted to accommodate the loads. So, if there were two 120V devices as a load, the line voltage would have to be 240V and if there were three receptacles the line voltage would have to be 360V. That's not very practical for audio.
