Would a P10 upgrade over Power Plant Premier offer any sonic advantages? Regards (considering the ppp is adequate for a setup even without it turning on its fans)
The short answer is “yes.” The P10 does everything the PPP does only better. The fact your PPP is not straining enough to turn its fans on does not mean your system would not benefit from the greater reserves the P10 provides. The P10 also has other features the PPP does not which affect the sound, such as different levels of Multiwave. That said, the PPP is a very good regenerator and it’s hard to say how much improvement you would get with a P10. I’m willing to bet you would hear the difference.
I would agree with Steve, but it might be helpful to know how you are using your PPP currently, ie what you have plugged into it.
Sorry for late reply.
I am currently feeding my Pass Labs XA 30.5 amps, Ps Audio Perfect Wave MK2 and my Velodyne DD12 + Serve sub through PPP. It doesn’t turn its fans off and sometimes I don’t use the Velodyne at all.
Sometimes the unit resets itself and that’s a major disturbing factor cause it happens just in the middle of my session. I watched for the front monitors when the units resets itself sometimes the voltage is around 200 Volts (european version). The question is does the unit resets itself due to the fact the incoming voltage is out of its safe working intervals or is it because its internal reservoirs are depleted? Can U supply an answer to this?
P.S. I suspect that it’s a capacity problem cause it even happens when only it feeds the Passlabs and the DAC only and the amp does pull 500 Watts Max if I am correct and the DAC’s consumption is negligable at all.
To be clear, are you saying that the INCOMING voltage drops to 200 volts, causing the unit to shut down? If that is the case, then the PPP is doing the right thing by shutting down, and the problem lies with the company that supplies your electricity. If, on the other hand, the PPP is only OUTPUTTING 200 volts, regardless of the incoming voltage, there may be a problem with the PPP itself.
I agree with 4krow. PowerPlants do have over and under-voltage protection so if the incoming voltage is out of range the protection circuitry should kick in. If the current draw exceeds the regenerative capacity of the PPP you should hear a click as the PPP goes into bypass mode (i.e., the regenerator is bypassed and you get filtered but not regenerated power). If that happens very much (other than when turning on amps, which can a high inrush on start-up) it’s a sure sign your load is too high. The output should always be 220 volts (plus or minus a volt or two and depending on the how the PPP is set up).
Hi; yes I was talking about the incoming voltage not the outgoing voltage to the units plugged. What is the operating voltage range for a PPP for the European version? Cause it doesn’t do this resetting sometimes even when the voltage is around 195 Volts but sometimes does it when the voltage hovers around 205 Volts, too… So I can’t get quite precise about why and when it resets itself.
So from Ur explanations, the PPP doesn’t reset itself if it runs out of reserves but just bypasses the regenerating unit to just filtering. So the shutdowns can only be explainable with the protection modüle kicking in, right?
As stevem2 pointed out when I turn on my amps sometimes I hear that click with the fans working for just 3-4 seconds and comoing to a complete stop. Meaning PPP choosed the bypass mode, right? So when the turn on rush passes Do I have to hear another click meaning the PPP went back to the normal operation mode (including regeneration)? Asking cause I never hear that second come back click sound. (By the way does the P10 Show whether it is in regenerating mode or by pass mode on its screen?)
Adding to my questions, how can I understand that PPP is running on bypass mode or in regenerating mode? (Maybe looking at imconing and outcoming THD and if THD outoing is lower…?)
It generally would not operate continuously in bypass mode unless your are really pushing its limits all the time. If the THD Out is lower than the THD IN I would think that’s a good sign that it is regenerating. On mine, I sometimes hear the tell-tale click when I turn on my old tube amp but that’s just for the in-rush. It goes back to regenerating faster than I can even look at any settings. I only hear it click once.
