If you become a regular of ASR, you'll save a lot of money. Much of the stuff tested fails or doesn't live up to manufactures claims.
I read that review earlier this week. Not encouraging for the AC regen curious.
I purchased a used Power Plant Premier(which is supposed to be their worst) for cheap here. Used it for 4 years, no problem, then had it refreshed by PS Audio 2 years ago. It should be good for another 10 years. My unit was manufactured in 2007!
$1500 total investment and I hear and see(when I plug the TV into it) what "clean power" can do. It's not jaw dropping dramatic, but noticeable. If anything, it made a good hub for the excessively priced, fancy power cords.
PS Audio regen units are just another "try it yourself and decide" box. Inline with audiophoolery.
The new models are quite pricey. Before such an investment, dedicated circuit and fancy outlet, along with overpriced faux carbon fiber cover recommended.
I was encouraged by reading this before I got the PPP
