Different use cases may dictate the requirement. You may end up with something like a non-current limiting Shunyata for your amp and a Puritan or AQ for your sources if you live in a city in an apartment building. Or even a regenerator like the PSA for all components. Depending a lot on what’s going on in the power line and what your setup looks like. I don’t think there’s a one formula fits all type conditioner.
I’ve used Shunyata Hydra for years then switched to Piritan. Two different types of design.
Since running a dedicated line, I actually prefer everything direct to outlets now using very high quality power cable on every component and plugged into Furutech GTX-D NCF outlets. My Puritan PSM156 is looking for a new home.
But…as with everything in this hobby…YMMV
