I just read that PS Audio has introduced a new and more affordable power plant, the Stellar Power Plant 3.
https://www.psaudio.com/products/stellar-power-plant-3/. I have been a long timer user of their various units, going back to the Power Plant Premier, then a P5, P10, P15, and now a P20. I was amazed at how much these bad boys improved my system and have been pushing them ever since to all my audio friends. Going from the P10 to the newer generation P15 was eye opening to say the least. Here is a link to my review of the P15

If the big boy units are not within the budget, then for sure try the new Stellar PP3. It can be used on all front end gear which is where they are most important. PS Audio builds and services all their gear in Boulder and are known for having a great customer service department. I do not think a system is running at its full capability without using one of their units. Try one.
PS: If anyone is concerned that i am working for PS, let me assure you I am not. I have a small menswear retail clothing store in Greensboro NC.
