APS Pure Power A/C Regenerators

Over the years I have tried a few power conditioners and always felt that they stripped the music of its "body," leaving me with a non-involving, non-musical, thin sound.

Because of this, I have only gone as far as a dedicated panel to dedicated circuits, with some above standard electrical hardware. ...and have been pleased with this results.

I recently had a conversation with a fellow audiophile, who also happens to be an engineer, who recommended that I look into the Pure Power line of A/C Regenerators.

He has tried quite a number of tweaks to his electrical supply over the years and could not say enough great things about Pure Power, to the point that he strongly felt that using this (specifically referring to the model 2000) in any standard outlet in the home, would outperform the improvments of dedicated circuits or any other electrical tweaking.

I am considering a project in my home that would move my listening room to a new space. Before I do this and before I bring in an electrician for all of the custom works, I am looking to hear from any folks that own or have owned a Pure Power regenerator.

Please share your experiences, both good or bad. Also, please comment on other A/C conditioners or custom/dedicated circuit topologies that you have compared this to.

Any experiences that you can share regarding APS Pure Power regenerators is appreciated.

Lastly, does anyone know if there is a performance difference between the different models, or do they only differ by their output capacities?

Thanks!

Why doesn't the power supply circuit in a typical tube or SS pre-amp or power amp self-correct utility power "Gremlins"?

I run ARC all-tube gear. Although there's not a lot of other stuff on the same circuit (i.e., from the outlet to the circuit breaker box), the ARC tube gear draws quite a bit of power even at idle. For example, at idle, the amp alone draws about 400 watts. Probably double that when it's "crankin."

I guess my concern is that if the consensus is that the PP regenerator is the way to go, a word to the wary, big $$$. Anyone know if there's a used market for that gear??

Compared to some other high-end filters that have NO isolation feature, I think the PP gear is incredibly well priced (remember, regeneration does away with the need for filtration and isolation). Plus are you aware that the retail prices of both the 1050 and 2000 have declined by $500 each recently?

They do show up on the used market but not very frequently. I suspect most people are pretty impressed with them and don't sell them unless they have a reason (upsizing or downsizing)

@bifwynne The reason most companies don't provide EMI filtering is cost plus the fact so many engineers and managers just don't get the fact it isn't "just 60 Hz" coming out of the wall.   If it was, there would be no need for any filtering or isolation.    Consumers vote with their pocket book, so adding cost requires selling that added cost.   One can prove it with graphs, data, independent testing labs, independent reviews, etc. but that doesn't mean the consumer will spring $$ for it.

Isolation is another animal.   Every component we buy is already isolated from the wall via its internal transformer.    However, that transformer is located inside the chassis so any leakage, stray magnetic fields, or EMI radiation will bleed into the unit.   Yes, it can be done correctly, but again, it adds cost.   The best solution is to put the isolation in an external chassis along with input EMI filtering.   Since a separate chassis puts distance between it and the audio gear, the bleed energy is automatically reduced by the square of the distance between the components.   That is hard to do when everything is in one chassis.   

I design and build some of my own gear but frankly even in my stuff, the EMI filtering and isolation is in a separate chassis along with an external power supply for the audio unit.
