PS Audio 600

Your description exactly matches my experiences. I'm glad I'm not the only one who likes this device. I'm surprised (and pleased) that it handled your four 135s. Did you play at 'realistic' levels?

BTW, the Accuphase is not a true regenerator and doesn't work on the same principles as the PS Audio.

What's the difference between the Accuphase and the PS Audio?

No, the PP600 let's through no pollution (unless it's on the earth wire - manufacturers are not allowed to fidle with the ground). In fact it lets through none of the original input power wave at all. What you are hearing is almost certainly RFI emanating from the switch or lamp element if it's fluorescent.

Ron:
Yes, 45rpm via PP600 on an armageddon works great. As you my know, all PPs have a frequency setting specifically for 45rpm (81Hz here in the U.S.)

Trust your ears.

David, please let us know about your experience! What is "proper rating" in your opinion?

Qoute: What you are hearing is almost certainly RFI emanating from the switch or lamp element if it's fluorescent

Mark: It's an ordinary 40W-lamp without earth wire; I guess the noise is coming from the small flashes when switching with that really inaccurate switcher. But how does this lead to RFI?

Re:

>But how does this lead to RFI?

That little spark does cause the RFI. For a full explanation, you need to take a look at the 'new quantum theory' but take it from me*, it's the culprit.

*Unless you'd like to learn to solve some very zesty math. Schroedinger wave equations? - Pah! Child's play ;-)

Dave, it's much *more* dynamic when properly sized. Maybe you just had a bad experience with the one you tried? When Chris K. next comes this way (Dallas) I'll see if I can convert him.

"It's just not as dynamic" without any explanation...?

Wondering..., - Jun

P.S.: it's much *more* dynamic when properly sized - - what does "properly sized" mean?

What I mean by 'properly sized' is that the equipment plugged into the PP will not draw more power (under reasonable listening conditions) than the PP can provide.

This leads us to whether the transient demands of Naim amplifiers could cause a clipping effect in the output of the PP. Experience so far tells me 'No'. I've only got a 250 but I've never heard any compression effects, even at serious volumes. Also, the PPs have a *very fast* output protection cut off system. Many people on the PS Audio forum who use tube or big class 'A' amps have commented on how effective (and annoying) this cut-off is.

Mark: When the whole system was plugged in the PS Audio 600, the display said 90-100Watt consumption, when playing really loud it never came close to 400Watts. PS Audio 600 is supposed to provide juice up to 750W.

Quote: even though this is a power generator and not conditioner.

So what is the difference between a power generator and a conditioner?

- Jun

P.S.:

Suppose one plugged an LP12 into one of these instead of running it through a Lingo/Armageddon? [...] Or am I missing somthing?

ejl: I guess the motor in your LP12 is not running at 230Volts, that's why you need a device which provides low voltage for the motor.

Jun,
FWIW, PS Audio's own explanation is here:
http://www.psaudio.com/articles/power_conditioners.asp

Thanx for the link, but I don't understand this kind of complicated explanation...

I guess that a conditioner does some kind of filtering; thereagainst a power regenerator is something like a power-station which builds a clean sine curve and amplifies it to 230Volts/720Watts... That must be the reason why the proper sizing is important...?

As I've previously posted,for some reason the PP300 doesn't sound as good as the PP600 and PS Audio have said that the PP300 will only work with the smallest of power amps and a NAP150 doesn't fall into that category.

Also, the PP300 only has four outlets which are all from the same output 'channel' within the box. This means that Mr. Tibbs favorite problem of the power amp modulating supplies to other components is an issue with the PP300 but not the PP600 which has two isolated 'channels'.

MrI: How was the result with the NAP150 unplugged from the PP300?

Qoute: Four of us got together once to try the PS Audio 300 and we attempted all of the configurations. The only thing that worked was the Planar 3.

So it does reduce dynamic even if the power-amps are not plugged in? - Unlike poweramps, sources ( & pre) would demand juice continuously: so I wonder how a power regenerator would affect dynamic if the poweramps are not plugged into it...

I don't want to give up any dynamic in my system, but I did like the reduction of restlessness, of roughness and the improvement of clarity.

- Jun

I've owned my PP600 for about 18 months now and have done plenty of experiments. With my set up, the system is definitely more dynamic and faster with the PA Audio in place, - irrespective of whether my 250 is plugged into it or not.

In many countries PS Audio have a 30 day return policy. If you're serious, I'd look into that before purchase, - just in case I am a deaf SOB ;-)

I'll e-mail you privately in a day or two (too much damn work right now!)

The system does not work with cd5 and flat into the ps300 (separate circuit)and the hicap/150 into one of two dedicated circuits. The bass was very slow and disjointed from the rest of the music. The acid test was cut 5 from Herbie Hancock's The New Standard cd. The whole tune lost its coherence.

However, put only the cd5 into the pp300, and I can't give you an answer yet after 2 hours of listening. Obviously it doesn't wreck the timing
or the sound. It is subtly different, perhaps a touch reticent in the treble and fuller in the bass. But no cd I threw at it was fundimentally destroyed. Now don't ask me to explain or understand what I heard, but there it is.

For me it's been best to get used to a sound and then remove the change to really verify the benefits or problems. YMMV. So I will report back in a couple of days.

Also, the pp300 will be left on standby, requiring the cd5 to be returned to its own dedicated circuit as the PS Audio products give off lots of heat in exchange for keeping your electrical utility happy with your bill if you leave it running.

I just want to add that I was quite surprised that the CD5 sound was not destroyed as it was when I previously tried my CDX

So last night I took off the PP300. I was surprised at my reaction. Although the "sound" of the system was worse, thinner with less bass, and the instuments were a bit "smeared" in space and timbral characteristics, I would have to say that the music was more engaging. I wish I could explain it better, because although the timing was not wrecked by the PP300, it obviously did something to affect the presentation in some way.

Therefore, I cannot simply slag off the PP300 as a potential way to improve your source. It is dynamite on a Sony cdp or dvp and super on a TT, but you need to hear the results on your own system to determine if it meets your sonic objectives.

I am likely going to forget it, but YMMV.

Last night I swapped some equipment around an found the best sound is with the hicap on the cd5, flat2 on the 112 and the cd5 and hicap into one of my dedicated circuits, with the flat2 and 150 into the other. Although they share the same electrical ground, for some reason, the system sounds better this way. No PP300 at all.
