PS Audio Ultimate Outlet and Power Director 3.5

Do the PS Audio Ultimate Outlet and the PS Audio Power Director 3.5 sound the same? Or do the extra features incorporated into the Power Director 3.5 contribute to degrading the sound quality compared to the bare bones Ultimate Outlet? Thanks
I use both in my system at the current time. I really can distinguish any difference between the two. I do plan to add a Running Springs down the road when the funds arrive.
