I had the PS Audio Ultimate Outlet and a PS AC outlet (in the wall) in my main system several years ago and never really heard any improvement. As blisshifi suggests give them some break-in time and then if you don't hear any improvement you know it's time to move on.
Couple of Line Conditioners...
Hi - So have had my gear plugged into a Welborne Labs, Gatekeeper for a long time with really great results. PCs are Audience PowerCords all around into tube amp, tube pre and tube DAC. Streamer plugged into the Gatekeeper as well. Picked up a couple of PS Audio, Ultimate Outlets yesterday just to try and mix things up. Also have a PS Audio outlet in the wall and use an incredible Ventus Audio PC to connect the Gatekeeper and now the UOs. I’m kinda disappointed in the PS Audio units... they are the upgraded High Current models too. Guess my question is - anyone use one or both of these to connect their system? What were your findings. All pieces are over 10yrs old but they seem HQ and as I stated, the Gatekeeper has been a wonderful piece for a long time. - B
