have looked into a shunyata hydra 4, ps audioand monstercable hts 2600. are there significant differences.
monstercable seem to offer best value.plan on hooking up
an integrated amp ,cd player,turntable and phono stage.

i dont think i have one but a few salesmen ive talked to recomended one for surge protectionand have also stated that it would improve the overall sound of my components.they especially recomended the shunyata but i had looked into the monster cable conditioner mainly because of price. i cant actually quite understand what they do.
If you need surge protection (and our needs for it vary from slight to significant), you are best served by getting a whole-house device connected right at the service entry near the breaker box. This will let it take advantage of a very low ground resistance.

Improve your sound? I think it's unlikely but you can experiment once you have surge protection off your mind.

Unless your sure you need it,invest in some other area of your system. Its too complex an issue unless your prepared for frustration. You may hit it on the spot righ away or just keep changing them until you have to sell your house!
I would certainly make sure I had dedicated lines and good quality wall plugs ( Porter ports are a good start ) first before I invested in Conditioning...good luck
I don't agree in whole with the responces. See if you can borrow a good one from a local dealer.--AS an example if I loaned you my Adept response you might want one.--
My experience with PS Audio products - starting with the P300 - has convinced me of their benefit. As others above have stated, you may or may not need it, but I definitely feel that my system has been improved. As Avguygeorge suggested - try adn get a demo. I think PS Audio still offers a 30 day in-home trial for their products if you don't have a dealer nearby.
