When you request info re. BEST--- there's a lot of room. If your ears and system are up to it I recommend the brand I use. This, after trying MANY, Inc. Monster,Chang,Audio Magic-(2 dif. models) and many other pricy ones. Monster,(AVS200) and Tripp ;-- not to much help 4me. The brand I use is a "whole-system" conditioner. It has 6 duplex outlets. Oh' the good news--only $3800-- Right now on new today there's a used one--$2400--not mine nor a friend of mine.
One hard task is my Mitsubitsi 65'w/ 9" guns, CRT,tv. All the mid priced ones did zip for pic.quality. This one does video picture and audio quality at the same time; all being on at the same time.I run CJ8 mono block and the music doesn't get better if the tv gets turned off/nor does the pic. degrade when the amps go on.-- I have no idea but I would guess there might be something better--but I would guess it be more $$.---Post what you got if you want. Otherwise don't ask for best---ask for best in your price range.
