brulee fails PC challenge

Big mouth brulee failed the PC challenge. Never had any doubts that the better PCs could make a difference. I know they can and do. Thought I would give it a try just to make sure big mouth knew what he was talking about. There was no pressure. I was all alone. Switched out the FIM PCs and put in a couple Beldon PCs. Just as I thought. The magic was gone. This is going to be easy I said to myself. Put the FIM back in and it sounded as bad as the Beldon. Images were stuck to the face of the speaker and was very dry sounding. Next day I listened again and all the magic was back. Big, liquid, flowing music was back. Swapped them out again and same thing happened. How can I take on this PC challenge when it takes the next day or at least several hours before the FIM PC comes around. I failed this test. I am convinced PCs make a subtle to dramatic difference but I still failed the challenge. I am very happy no one was there to say "I told you so". I am a believer in PC but what can be said of someone who constantly touts the benefits of PCs and then fails the PC challenge. I'm glad my friend Jhunter was not around. Any ideas to keep things stable? PCs do make an improvement, just ask the guy who failed the PC challenge. Any help would be appreciated.
