Hello, I have 2-300 powerplants and love them. I also have a 20 amp Ultimate Outlet and I strongly urge you to give it a try. I have a new Classe 301 amp on it and they sound great together. Most PS Audio dealers will give you a 30 day in home trial with the Outlet, so what do you have to lose except a few bucks for shipping? One word of caution, dont expect to get blown over right out of the box, let it burn in. Take at least 3 weeks to listen to it and then remove it and see what you think. It does not alter the sound of your amp, it opens it up, cleaner and darker background, more air around the music. I enjoy it.
Good Luck to you & GOD BLESS THE U.S.A. !!!
