is there an alternative to PS AUDIO

As I've mentioned in another thread, Powersnakes (Shunyata) is expected to launch a type of conditioner/power regenerator in Sep which is purported to eclipse all existing gear. Currently, it is anybody's guess whether it will be a meaningful improvement. The little I know is that it will have similar capability of the PS Audio 600. Based upon the excellent benefit many have noted with their PC's, I'm hoping their new device will uphold the company's reputation.

Yes. There is another company that makes a similar product, however it costs MORE! See Widescreen Review's site for an article that reviews all the major line conditioning products. You might try the PowerCompany products. They can provide similar benefits in some systems. To you PSskeptics. The PSAudio line is very much a YMMV product. The benefit you notice depends on your system's ability to resolve detail. The higher end the system, the greater the percieved improvement. It also depends on the quailty of the power in your area. When you get into true high end (which seems to start at around $15K...) the difference is well worth the $1K price tag.

The PS Audio is a tremendous product. Although it doesn't directly relate to sound quality, one of the things I like about the P600 is that its operating principles are logical and straightforward. It's good engineering as opposed to what some other product types offer. Accuphase makes a similar product, but I think its price is in the $8,000 area. Within the context of my system (Pass amplifiers and Wadia digital) the P600 is flawless. However, I suspect its benefits are strongest on front end components. As with any tweak type product, give it an in house audition. PS Audio policy is to give a 30 day trail. You can't go wrong with that! I personally think the P600 is a bargain.

There are a LOT of AC power supplies out there in industry, the PS Audio Powerplant does the same thing(according to the Stereophile interview). I used to use a lot of these at a former company. They are not cheap(but not normally $8000 either). I don't remember the companies who make these products, but if you are interested you could search: 1)the Thomas register(a series of catalogs used by American industry - like the B to B Yellow pages), 2)on the web, or 3)ask an electrical engineer. Oh, one more thing, the faceplates on these units are not meant to impress audiophiles, they are industrial equipment. So if you are the type of person who buys equipment for looks, you are sure to be disappointed. On the bright side, you won't have to pay audiophile prices(whatever the market will bear)/markup either.

I am using ONEAC (power conditioner) on my front end. This unit has the capacity for Transport to Preamp. I am happy with it, but I have nothing to compare it to.
