I have tried my main components with and without a conditioner. The amp sounds better plugged straight into the wall, but the CDP sounds better thru the Quintet. With the CDP plugged into the wall outlet, I hear the soundstage as images in my room. With the CDP plugged into the Quintet, I hear the the images in their room. What I mean is that I hear the musicians in the room it was recorded in. I want more of that. BTW, I would also be interested in feedback on something like an Oyaide power strip compared to a power conditioner.
