Seeking advice re: complex power conditioning

The PS Audio unit, as stated above, is a vastly superior solution to any other type of power conditioner. I will throw in another solution equally as expensive and even more demanding of space, but better than all of them put together: A motor-generator, aka a big electric motor hooked straight to a big electric generator, available from several industrial motor and phase converter manufacturers. They run in the multi-K range and need to be isolation-mounted somewhere far from your listening room (garage for example, or a separate shed), but will provide an absolutely perfect waveform with tremendous current capacity, and 100% total line-to-load isolation, meaning that ANYTHING coming down the line WILL NOT make it into your system. Plus they're very power-efficient, usually around 90%, rather than the 25% or so (just a guess) that the PS Audio will run. Just something to think about....

Thanks Pls1, good post.

Re your hydraulic pump, the vast majority of the noise/vibration is coming from the pump side, not the motor (my guess would be on the order of 99%). Like I said, you definitely have to mount this system with isolation mounts, or put it in its own shed, but most are not that noisy since they are no noisier than two AC electric motors.

Re efficiency, I was just assuming 95% efficiency for the motor and the generator, which may be a little high, since the smaller ones probably aren't that good. So you may be right, 75-80% may be more accurate. Still way better than the 25% of a class-AB amp like the PS Audio unit.

For Tekunda, sorry if the above wasn't adequate explanation. A motor-generator is two separate pieces, (1) an electric motor, and (2) a generator. They are mounted facing each other on a single platform and hooked together by a straight coupling to transmit the rotation of the motor into the generator, which then creates the new AC waveform from scratch, just like a miniature power plant. They are completely electrically isolated from one another, which is why they give such good performance-- the power company's AC signal ends at the motor, and the generator creates a brand new one. I didn't point this out before, but they are immune to short-term power interruptions as well (up to a few seconds), since they carry a lot of inertial energy in their rotation.

Yikes, I wouldn't go there unless you live in the middle of nowhere and have a gigantic piece of land to put it on the other side of. Talk about noise, vibration, and stink too!

I haven't looked seriously at any of them-- while I think it's a great idea, I haven't had the desire or ability to try it. But for someone who telecommutes or has a home business, it could be a perfect solution and a tax writeoff-- you need clean power for your computer too!!:-) Try Kato or Horlick, probably can find them in a Google search. I'm sure there are others as well, ask an electrical contractor with hospital experience.
