To add to this discussion if I may. The Corelli is a marvelous unit, all of the reviews are accurate and it is the easiest upgrade to use ever.
I have it plugged into a simple but robust power strip made by a company called BPI, the remaining components simply plug into the same strip.
I have used a lot of gear, lots of power conditioners from Shunyata to PS audio, several from IsoTek, and many others.
The Corelli is simple and works wonders. It seems to produce an overall improvement in all areas as opposed to “more bass” or “better image”, it improves all areas. Very easy to install and easy to perform with / without comparisons. When I have had audiophile colleagues visit their responses have been consistent. Easy to hear the difference and if given the choice would not want to listen without the unit in the system.
The only previous product I used that was similar and was very good as well from Nordost. The QX power purifiers were great and produced a similar result to the Corelli. Problem was that they doubled the number of power cords you needed and they suggested multiple units. I used to have 3 of these.
The Corelli does it all in one box and is as easy as just plugging it into your existing power distribution.
I would suggest getting their power cord as well, it seems to be an important part of the performance.
Additional benefits can also be had using Akiko’s “tuning chips” . I have been using these on power cords as well as what they call a “harmonizer” that connects to the ground wire of my electrical panel.
Very cumulative improvements and a real synergy when I began using these things together.
I have no financial interest of any kind in the Corelli gear, people seem to be mentioned such things in their comments. But I am a giant fan and wouldn’t be without the Akiko products I have added to my system over the last 8 months or so.
