The PS Audio products are current limiting and choke down the sound. The do quiet things down a bit, but the expense of what is lost is not worth it.
I did not get a chance to spend a whole lot of time with the Audio Magic Stealth (1 week with a broken in unit), but my experience was that of being underwhelmed to say the least. It probably is a good value at the price, but that is it.
The Sound Application is excellent. It can sound a bit lean and thin in some systems, but it really does a good job.
The HYDRA is my favorite out of the bunch. It limits nothing and allows everything you want to hear come through. Although I am a Shunyata dealer, I can say that this recommendation should be taken seriously because they are not available anymore. There is a new model called the HYDRA Guardian (?) which will be out in a few months. I cannot comment on it as I have not heard it yet. What I have heard is that it is projected to be quite a bit less expensive than the HYDRA with uncompromising surge protection to boot.
Another recommendation I have which is not on your list is the Jena Labs Fundamental Power 6.1. It is an all out assault on power conditioning and has done amazing things in my system. If you decide you want to listen to it, I am sure I can setup an audition for you. The only drawback is that it is very expensive. The retail cost is 6k.
