PsAudio 300?

I was looking at some power protection/cleaning as well, also thinking PS300 or 600, and read the comments with interest.

What do you guys do for your amps, if they aren't plugged into the PS units? I was kind of wondering whether I'd cross their power limit with a pair of ARC VT100s (bi-amped for main spkrs) and an ARC D240 (surrounds). I'm also curious, for Martin Logan owners (or other ESL owners), whether plugging such speakers into a PS300/600 has helped...

I have been following the progression from Power Plant since in was introduced. I went to my high end dealer and told them about it and was blown off in a way that made me finally realize these people were snobs...4 months later they started carring the product. Anyway, I think PS Audio's design and philosophy in the PP series in rock solid, however the PP does not address line hum caused by the neutral/hot/ground config of our electricity. I have since bought a Cinepro Power Pro 20 and love it. I'm sure the PP will do what it claims to, but again, it doesn't do it all. Read about balanced power before buying.

Power Plants output balanced power,as well as voltage regulation,regeneration,etc.

Are you sure about that N_2?

This is from PS Audio's website:

The Power Plants are NOT a filter or balanced transformer. These are actual AC generators that produce perfectly clean AC power under ANY conditions, even when the incoming AC is clipped or badly distorted - something no filter, power line conditioner, or balanced transformer can do.

I have owned a PowerPlant 300 for over a year now. When I bought it, I was a skeptic. I found it here at a good price, and figured I would try it, dislike it, and resell it. Here is is a year later, I am keeping it.

I run my CD Player and Pre on the PS-300, set to 90 Hz frequency, which seems to yield the best results. I do not have a fan or multiwave option, and I do not see the need for either. (The fan makes noise, I did not hear much difference on a PS300 that did have multiwave). My unit runs at about 110W output continously, and draws roughly 170 watts input, both meassured using a watt meter. So, your electric bill will be a touch higher. The unit gets, you guessed it, nice and warm. I have had more equipment plugged in, and just was not as happy with the results when the unit was running at 250W output; music seemed a bit less vibrant.

Another note, I run the unit at 90Hz output, which seems to yield best results with my CD player. However, there is a very slight audible buzz from the transformer in the CD player. (Very slight meaning: I put my ear on the CD player, I change the frequency from 60 to 90, and I hear the buzz become higher pitched and perceive it as being louder).

Overall, it made the quiet passages quiter, seemed to make the highs a little crisper, and the bass became a little tighter I think. They're small, but pleasing changes. I think I paid about $600 used for mine, and consider it well worth it.
