Looking for the best power conditioner or regenerator or any product like it for under 2k.

Just keep things in perspective,

A Capacitor can load itself up with the dirtiest power in the world, it's output will be ....

@clearthink Really don't follow your comment or how it relates to my relatively innocuous and demonstrably true statement (about opinions varying about various power products).

Opinions on efficacy of these products varies a lot, probably due to both subjective and objective factors. I remain curious, myself, but to at least do the minimum, I put in dedicated lines. After that, I would likely want to get something well-regarded and used, so that if nothing comes of it, I can resell. (Or get something on a trial basis.) 

I think the EquiCore 1800 and DeepCore 1800 have a circuit breaker, which many people thinks sounds better than a fuse.

Keep in mind that ALL power passes thru the tiny fuse wires.

Next consider that the energy stored in the Capacitors is the source.

I also have a EquiCore 1800 and DeepCore 1800 and was surprised at how large a difference it made.  I was living in an NYC apartment at the time.

There is a used pair for sale for $1800 on another site right now.

Plixir, but shipping will cost you these things weigh a ton.

Fully balanced power supply.

Hope you have a dealer nearby.

@mgkaye ,

I got in at the beginning as soon as Rick introduced the new product line. I bought a pair of MC-0.5's on sale. He hadn't introduced the more advanced Helix yet. I added the DeepCore and system was sounding great. I eventually added two more MC-0.5s and a  CT-2 digital cable which was not cheap. So i didn't have any more funds.

@lowrider57 Thank you for the reply. I have heard some others who love to use many of the MC power modules, even stacking  MC-1 pro double helix plus signatures on each other. Why did you decide to use multiple 0.5s instead of one of the more expensive ones?

I first bought the EquiCore 1800 and it performed very well lowering the noise-floor. I then added the DeepCore 1800 (on sale at Underwood) which added an even greater benefit at lowering noise, RFI/EMI, plus added surge protection. It was a dramatic improvement which made my system more revealing.

I also have 4 HF MC-0.5 power modules plugged into my 2 dedicated line receptacles. These provide remarkably improved soundstaging and imaging, smoother digital playback, and increased detail and realism

I have no experience with the Niagara but I know it’s highly regarded. One of the High Fidelity power conditioners should also be considered, they're priced over $2000 but are on sale periodically.
