Best power conditioner for 300.00


I have a dedicated 20 amp circuit run to a hospital grade outlet for my system. ( Electronics are Krell and Speakers are Dynaudio ) I love the sound but I like to leave the system on and I am a little worried about spikes or surges. So I would like to put something between the outlet and my electronis. I don't feel the need to go crazy because the power is very clean as is. As long as I am going to get surge protection I might as well get a little conditioning. I have looked at Chang Lightspeed , Audio Power, and Tice. I would appreciate any feedback. Thanks in advance- Brett

PS: If you can muster a hundred or so more, look at the Blue Circle BC-84 at $390 list; the Blue Circle BC-83 at $490 list; The BC-84 is a higher end product than the BC-83; it is a two outlet conditioner (with Hubbells). Also in that range is the regular (not reference) Vanevers 83, 85, or Unlimiter.
I recently picked up a used Chang 6400 here at Audiogon for $250. I'm quite happy, it improved my sound, and I feel safer.
