You won't know until you try a power conditioner in your system. And you won't know which one until you try more than one. You really can't go by what others say. I mean, of course you can. But you won't know what's best for your system.
And, btw, you should also try without a conditioner.
I was surprised when I went directly into the wall. I have a new home so maybe that had something to do with it. My next step is dedicated circuits and lines for my front end and the amps. I know this is not possible for everyone--and believe me, there is a WAF also in the mix. But that's my next big goal.
(And, yes, I know there have been a lot of advances in conditioning. I had been using a Running Springs Dmitri for my front end and a pair of PowerCells for my mono blocks; sub amps were always direct into the wall.)
Either way, I don't think I'll go back to power conditioners. Just sounds better without them. Dedicated lines or bust.
Food for thought: experiment and find out.
