P20 now available for pre order. Delivery early April.
I am not sure whether my question has been asked with the P20 but I am sure that it has been asked with the ‘old’ model.
Is there any DC blocker in the new model, I believe there was none in the old one.
If no, can you give maybe an approximate likelihood of the DC blocker being useful?
I know it depends on the mains power but is it 1% likely to be needed, or 0.1% or 0.001%, or maybe 10% of the users?
Thanks.
Bruce
All of the existing PowerPlants block DC. I expect the P20, plus the new P5 and P10, to all block DC as well.
Thanks for the clarification.
And Big thanks for replying so promptly!!!
Bruce
Yes, the P20 and new Power Plants all have DC blockers.
Paul, in an ideal set up. Would I be better off with 2 ( new version ) P10 units or a P20?
P20. 
Paul
Paul, can you share with us why? I am under the impression the new upcoming P10 is built like the P20 just with less output? Or this this false?
Would this also be true if the 2 x P10 are on a dedicated cirrcuit each? The P20 would obviously have to go on a single circuit. Also, wouldn’t the P20 push the limits of a 20A circuit. What is the AMperage of a P20?
Does P20 operate silently? The buzzing noise of P3 slightly annoys me occasionally, sometimes to the extent that causes me to contemplate changing it for one of the new models (should they be silent).
Yes, completely silent but I am surprised about the P3. If it’s buzzing inside it likely means there’s some DC on the AC line making the internal power transformer buzz a bit.
My P3 is connected to a HB3, so there is no DC on the AC input.
I am not certain what an HB3 is but if it makes sure there’s no DC on the AC line then I am at loss to explain why there’s an internal technical buzz.
HB3 = PS Audio Humbuster 3.
That should then be fine. Hmmm. Stumped.
It has always made a loud buzz…previously it was installed in a server rack so the enclosed cabinet contained the buzzing noise. When I bought DMP + DSJ, which aren’t installed in the server rack, I decided to move the P3 out into the open to sit next to its new siblings. It was only then that it became apparent how loud the buzz was, clearly audible throughout the whole room. So much effort went into the re-wiring of the new arrangement I couldn’t be bothered to revert back to the quieter way it was before. My PPP, P5 and P10 were all silent.
Another P3 owner recently commented on the forum about his P3 buzzing. I just assumed it to be the way they were. I’ve only owned one P3 so had nothing to compare it with.
I wouldn’t say false. Perhaps incorrect. The P20 is a different beast. It has twice the energy storage and output transistors than the P10, which means half the impedance. This is important for sound quality and anything connected benefits. We were just in Chicago yesterday demonstrating the sound quality difference between the P20 and older P10. It didn’t take anyone in the room more than a microsecond to hear it - and we were just powering a set of M700 monoblocks. They didn’t even move the P20s (or the P10’s) power meter.
Moreover than just more, bigger, and robust, the P20 has an all new designed sine wave generator using DSD rather than PCM as well as a completely redesigned output amplifier stage.
Yes, it is a far different, better, beast.
For $14,495 AUD the P20 costs almost as much as two P10. So it makes economic sense as well as technical sense to use a P20 instead of two P10.
I know this is silly, but I bet many would get a kick out of seeing the power meter wiggle even when they are using little of the capabilities of the unit. Perhaps in a future software update you could offer a choice of range for the meter.
Great suggestion though can’t pull it off. Truth is the big screen for the P20 chews up CPU from our weak display driver and we take time to write the graphics. You wouldn’t notice it when just using it, but going with live meters means we’d need much faster frame rates which our display electronics can’t support. The team’s working hard on redesigning display electronics so future products can actually display video if needed.
