I had the PS 300 and then got the Hydra. Kept the Hydra and sold the PS 300. No comparison. Balanced power,voltage adjustment or not.....the Hydra is better even without these features. It is passive. IMHO

I have tried both the P300, Exact Power, and Equi=Tech.
P300. I think the P300 is a good product, especially at Audiogon prices--I have one up for auction now. Made a big difference in television quality and virtually eliminated noise from my CDP and preamp (the main culprits). As I stated in an earlier post on this subject, I think the reason so many come up for sale is that PS Audio has sold so many of them (a positive rather than negative reading on your observation). And the P300 is an entry-level unit so, after trying it, many upgrade to larger units.
Exact Power. I had a few concerns when I ordered this product given the lack of reviews. However, my experience is consistent with the review on the Exact Power site. I think it is a nice product which really does the job. You can hook up a lot of gear to it--far more than my circuits could deliver power for. I live in an apartment with poor power so it may bring greater improvements given my situation than yours. And my system is not overly power hungry so perhaps others can comment on any dynamic limitations this product imposes. One issue which I have heard raised is that downstream transformers may hum when attached to the Exact. I have heard this about the Power Plants as well so this may be common to power regenerators. I have noticed this with the Exact but it is quite minor.
Equi=Tech. Another nice product. Cleans up the AC well and generates balanced power. As you say, it will not adjust power voltage or frequency. A nice touch in my system following the Exact in the chain. But the Exact would get you most of the way there.
Good luck. --Scott
They're very good units, but are inefficient because they require so much power themselves that even the biggest ones really don't work on large power amps. I had to use a Richard Gray unit for those. Eventually it was just easier to get rid of both and switch to a Burmester 948 (expensive, but takes the whole system).
I agree with jbweaver, I think they have sold lots of them and many people(a couple I know) have upgraded to bigger ones to put more stuff on them. I have a P600 and really love it. I have everything except my power amp hooked to it (including my Pioneer Elite Pro97 rptv). It makes a huge difference for the tv. Maybe you can just get another p300 for the tv, or upgrade to a p600.
I had both the P300 and P600. Both had multiwave, and I ran them both from dedicated outlets. The P600 was switched to 220V, which made it perform better. Both were fed with high quality power cords. I was using the P600 for my amp and analog, and the P300 for digital. Then I tried the Sound Application C-FX. My system totally opened up, and I realized how the Power Plants restrict current flow to audio equipment. Yes, they quiet things down, but they also mask a lot of nuance and low level detail. Recordings now had space and venue that was lost with the Power Plants.
Then I tried the new Audio Magic Stealth. I didn't have much hope for this lightweight power conditioner in a plastic box, but compared it to the C-FX at the urging of it's designer. WOW!! It smoked the C-FX. Out went the C-FX and in went two Stealths to isolate digital and analog. This is the best I've found. The silence and black background is stunning. If you follow Soundstage, you'll see that some of their reveiwers are using them now in their reference systems. The owner of Audio Magic hasn't advertised these things, and he can't keep up with the demand from word of mouth.
Glreno, I saw your post concerning the Audio Magic Stealth. It really blew away the CF-X. I wonder if the CF-XE would complete better. I'm in the process of selecting a plc and was wondering if you could provide the main difference in sound when you put the Stealth in place. Was one Stealth better than the CF-X or did it take two? Was also wondering when you installed the second Stealth to separate digital, was the drop in the noise floor significant? What is the list price for the Stealth and do you need to but directly from Audio Magic? Thanks in advance for any info.
P300 does not deliver enough power for any amp, even my integrated B60. By this I mean, it restricts power flow and you notice that dynamics become too tame and flat -- not dynamic in other words. If you don't care about dynamics because your gear does not have good dynamics, then you won't notice the problem. The surprising thing to me is even when hooked to source stuff, the dynamics were affected -- maybe just because I had the P300 plugged into the same line as the amp! But, on the other hand the P300 did sweeten the harmonics nicely, so that's one plus.
I used the P300 for a few years then one day just plugged everything into a cheap extension block, after hearing the difference i never went back to the P300 i found it killed the dynamics when compared to a cheap budget extension block.
Now i use a Running Springs Dmitri which i plug everything into my system sounds fantastic, i believe passive conditioning is better than regenerating probably now everyone is realising this and selling on their re generators,
To anyone with a re generator plug everything into a cheap extension block and compare the sound it will cost you about $10 you got nothing to loose and could end up cashing in the re generator.
