P20--arrival and installation

I am amused with my situation. Now that I have the big Gryphon amp plugged into the wall my monster P20 is currently providing less than 200 watts of power to the gear that is plugged in it. Headroom, oh hell yes I have headroom.



My P20 provides a bit more than 200W with everything on standby. :slight_smile:


Thanks Al, that’s useful to know, so it sound like a pp3 will do if I don’t plug in pa & speakers.

Why don’t you plug in your pa into the P20? Do you find it sound worse when plugged into P20?

Must be the (tube) heaters, :smiley:

Some time back I added a P12 to my system and the change was ‘not subtle’ in the least. To say the change in SQ was dramatic would have been an understatement. Having my amp at the time blow-up (ML 333) I elected to go the mono route and picked up a pair of Pass 260.8’s, and unfortunately the P12 was no longer up to the task, so I got a P20 for my main system and the 12 went to my second system where again it performed its magic. My only issue with the 20 is that I had to run my pre to the outlet (different line) as the P20 would trip when I started the system via remote. Tried a bunch of things, starting pre first (ARC Ref5se) then amps, amps first then pre then DSD, but 50% of the time it ended up tripping. I would either need to delay amps for 5 minutes while the pre was warming up or something so I finally gave up and went to the wall with it. Too bad tho, would have rather gone into the 20 with everything…wonder if they are going to build something a little bigger…maybe a P25…

My Amp runs in pure class A mode at all times. It has a two very large banks of Capacitors that grab a lot of power on startup. The company that makes it says please plug it directly into the wall, we take care of the power internally. I trust they do. I am not even curious about how it would sound with the P20. I believe many amplifier manufacturers say similar things.

I have more gear on the way and that will be plugged into the P20. I am temporarily running a simple setup.

Pass says the same thing.


It seems to me that a lot of people have bought the P20 and not used all the power or sockets, I understand, it’s tempting go ‘big’ so you don’t have regrets later. I think I shall rule it out for now. That just leave P15, P12 or PP3 :thinking:

There was a time I had all outlets full and it was the right choice. Oddly, now I have less need for it but seeing what a P20 gets on the used market I’ll keep it until I die. Worst case scenario I use it for a weight. There was also a time when the talk was that a P20 sounds noticeably better than any of the smaller Regenerators. That was the main reason I bought it. That and it looks so bitchin. I was stunned when I plugged everything in and it only needed to supply under 400 watts to all my gear. Now it’s half that.

Problem is that both pp3 and p12 have 4 uk sockets and p15 has 9. I want a p13 that has 6

I also adhere to Nelson’s advice and plug my 260.8’s directly into the wall. And yet… my friend has an X250.5 and an ancient Tice Powerblock IIIc (I think). For years he followed the same recommendation. Then he decided to try an experiment and discovered ultimately that the amp in fact did sound better when plugged into the Tice! No dynamic limitations, just sounded better to him.

It’s gotta make you wonder how the Passes would sound plugged into a P20. Unfortunately I have only a P15. But it draws only about 200W quiescent with just my line gear. :thinking:

While acquiring a P20 as more future proof is potential motivation, the P20 provides the best sound via lower impedance, higher headroom, etc.

On another topic, which some amp manufacturers state their amp sounds best plugged into the wall I would try plugging any amp into a PowerPlant to test this claim.


Chris5 … the beauty of your Quadraspire rack is you can buy different size spacers.
Additionally the spacers screw into each other so for example you could take two 140 mm columns, screw them together and you have a 280 mm spacer column.
I have the standard Quadraspire race with a good assortment of spacers and I mix and match spacers together to give me the shelf heights I need.

Right on Elk…

Mr Pass et all know how to design outstanding tol amps…but have forgotten
that an ac clipped sine wave will never be corrected by their power supplies…
no matter how stout they maybe…

As for class A amps being a burden to a P20…Baloney !!

Here is a link to an old post where the poster is running 2 Emotiva XPA 1
monoblocs in pure 60 watt class A, plus a Plinius class a on a P12 …YES
a P12…the P12 while working more than the norm still taking it all in stride…
Post includes pix of the power watt meter on amp boot up and then in use…

Now if a P12 can handle all that…a P20 would far outclass that…
My new Parasound JC5 being powered by my new P15 is super
happy with the regenerated power…

Hope ya’ll take the time to read thru and observe the illutrations !!

Hope this helps!!

Thanks for the idea. The max single piece height is 12 3/4 inches, would that be enough for a P20?

I think the P20 height is 11 inches?
You should be able to find out from the online manual.
I can’t check as I’m out and about.
As before, you can use two different height spacers to give whatever height you need.

Looking at the specs, there is only 800VA continuous load difference between the P12 and the P20 1200VA vs 2000VA. and in fact the spec shows the peak on the P12 is actually greater than the P20 which is bizarre!

I guess your are really paying the extra 5K for the number of devices you can connect.

I suspect sonically the differences are very small and certainly does not justify 5K for the P12 over a P20. I would probably prefer to buy the new Ds MkII With that

Yes, you are right, still increasing the height of my rack by that much may mean I won’t be able to reach the top shelf :wink:

Like anything, nothing is absolute. I’ve had 5 Pass amps. Some sound much better into the P20. Some don’t.

The difference is more than merely more outlets. :slight_smile:

Many have reported significant improvement upgrading to a P20 from a P15, and even greater between a P20 and a P12.

But everything is relative, as well as dependent on your needs and desires. It certainly may be a better choice to buy the upcoming DSD II than upgrade a PowerPlant.
