This is what I use ... Rackmount LCR 2400

It is way cheaper than Monster products and offer a little more. I will not comment on how good this product for fear of flame. All I know is that nothing dims anymore when I turn on my equipment. If someone really juices up the circuit (like fiancee plugging in the vacuum) I do not get the very quick off/on/off/on thing happening to all the equipment plug into the living room. It either works fine and dandy or just trips the Switch box and turns off all the circuit.

If you have a dedicated curcuit for your HT I doubt you will even need it.
