Plugging digital components direct to the wall here can result in contamination if the others are not isolated. This was obvious playing vinyl - it used to sound better when a CD player with a switching power supply was unplugged. An AudioPrism noise sniffer easily identified the noise it was dumping into the line which went right through the EP-15A.
In my case the bass is firmer from my current player when plugged into a power unit yet the player sounds a bit more open when plugged direct to the wall. Every other component I tried sounds better plugged into the Premier. With the EP-15, one of the amps sounds better direct to the wall (on a good power day). You really need to experiment with what you buy.
It may be that the reason my player sounds better direct to the wall is that greater isolation is achieved in my particular system than if it is plugged into the Premier or EP-15 and everything else is plugged into the power unit. It also may have to do with the difference in outlets used. PS Audio stresses the multiple layers of nickel plating on its outlets but I know I have not liked nickel when used in interconnects or binding posts.
I don't think the Premier or EP-15A power units are current limiting the player. Some people liked to load up the old P300s which would current limit far short of the load required to shut it down. This was fairly easy to identify with demanding recordings.
