Are you listening to the CD itself, a rip, or a Harmonia Mundi download?

A little different music that I don’t normally listen to.
I don’t have a Powerzone and am waiting for another high-quality power strip.
I didn’t notice any graininess in my system. Maybe I’ll listen to the pieces again with the upcoming power strip. I’m interested to see how much of a difference there is to my PS Audio P10 including SR master fuse.
Last week I compared the Synergistic Research Uhf 8 SE power strip.
I had the impression that there was a little less resolution than with the P10, but the bass range was more pronounced. The background was blacker with the SR. I would rate the comparison as a draw, depending on your taste.
I built my speakers myself and placed a lot of value on a high-quality crossover with components selected for sound.
I have a Mundorf Supreme silver gold oil capacitor as the main capacitor in the high frequency range. It was only when I gave the Duelund JDM Silver Bypass 0.01uF that I noticed that even the highly praised Mundorf Supreme SGÖ had a certain graininess and edge in the high frequencies in comparison.
The small Duelund JDM silver takes this graininess and adds a touch more air and openness with a beautiful silky resolution without any harshness or graininess.
If you have the opportunity, you should try it yourself. Affordable as a bypass capacitor but with great effect.
A Duelund JDM Cu/Sn is also a beautiful capacitor that delivers rich, organic tones.
And Luca, congratulations.
I’m looking forward to more impressions.
Yesterday I was able to hear the large PMC speakers with AVM components and a complete Audioquest Dragon cable loom at my dealer again.
The bass range was very impressive. Ultra deep, dry, clean and audible. A very high level. But it was only hi-fi and the music lacked emotional expression.
No comparison to the lifelike demonstration I was able to experience at Schnerzinger with the Grid Protector.
Was it the kite, the loudspeaker or is the AVM electronics technically to perfect?
It didn’t really touch me emotionally.
Greetings Andreas

If you do not hear an immediate improvement, blame your dealer friend that cooked it too much. 
@paul172 So, I connected the last spot from the Puritan Routemaster Route to PZ. So all units are plugged into it, and the RM is connected to a GM City to the wall. I do not use the 2nd City.
Well, maybe Luca can understand what I am talking about since he has GM, and I do not know if anyone else here has the same setup.
The SQ is great, but it has always been great for today so I dunno if it is greater. 
We are packing today, and I should not play around with the system now.

Do not know your system completely and I only understand half of what you said. Sounds like you need a PowerZone, and 100% you will hear improvement.

Thanks Paul for your precious answers from the “other Paul”
Hmm maybe Donald is lucky enough to leave early, otherwise he’d plug the PZ into the Puritan… and see what happens. And others might want to do the same with a P15/P20…

The ground connection is the last thing I would do today, and I may unplug it later. I am simply enjoying music today, no tweaking. But the system sounded better than yesterday, and I have no idea if it was from RM, or from continued break in.
What is your first impression?

Can someone please check that @dchang05 is ok?

Donald is enjoying his vacation first before he has to play around any more.
Maybe by then there will be new information about whether he should put his PS Audio P15 in front of the Powerzone.
Just in case, Progressive Audio says that they also supply their power station without sockets so that this generator can be integrated into the leased line.
I hope that the Grid Protector can solve all of your worries.
It seems that all Powerzone owners experience an improvement compared to the most commonly used PS Audio power plant.
The only criticism I have heard so far is that the high tones have a bit of grain. Perhaps this will improve over time. If not, it could be high frequency interference.
On the whole, no one seems to really miss anything compared to a filter or power plant?

Bass profoundly deep
Air around voices, that are more vibrant and a little bit forwarded but pleasantly more realistic
Tons of details, separation - from left to right something is catching my attention every now and then
Ease and quietness and relaxation
As per my dealer today should be day #5 - the best is yet to come… need to acclimate myself to this new sound, that is NICE indeed.

So… I wouldn’t be able to sell my P20 to partially fund a PowerZone…
Not that it would matter. Couldn’t afford a PZ even if I did!

So after about 120 hours of burn-in, I put the P15 in front of the PZ (P15 plugged into the wall and PZ plugged into the P15) and have been running both since Sunday afternoon (2 days).
It sounds a little darker and seems easier to listen to for longer periods as things burn in. After another 100 hours or so I will try taking the P15 back out to re-compare, but right now it seems the P15 is helping the PZ.

No worries! Even listening to background music, I could hear no improvement. It made the sound murky it seems. I removed the ground cable and will listen to it more closely if I have time later. Or I will just put everything on standby and not worry about it until I come back.
Luca can play with it (Add CAD or plug it in Puritan).

Wow! I really want to sell my P15. You are throwing a big curb ball before my trip.

Not true. This is Hafner’s observation and choice. Gryphon recommends direct to the wall PZ and equipment. I know Gryphon prefers this method because there is no way possibly to add or discolor the signal with a regenerator or conditioner. I have the chance to try the P20 with the PZ but I doubt very much I’ll be keeping it. If it sounds great without out and status quo with both there is no sense of keeping both. If there’s a massive improvement that’s another story.

I think it’s a by product of the PZ break/burn in. I also experienced some harshness and brightness on certain tracks. I’ve played them over to make sure it’s not a constant issue and it seems to rectified on my system. I hope it is a temporary nuisance and not a full-time lingering problem
Are you running off a 20a circuit? The PZ is designed as a 20a unit. I don’t see running it off a 15a P15 being beneficial. Could be detrimental? I’d check the owners manual on that one.
I have noticed and have commented on the extra grit that seems to ride in the treble region as well as an emphasis in this region. The grit has tamed down considerably and there has been a slight de-emphasis in the brighter high end.
Not perfect in my estimation, but trending the right direction. Maybe the fourth week will be the charm.
I also content that this treble bump could be a byproduct of a unit that reveals all, suggesting the P20 could have darkened the sound a bit. Don’t know, time will tell.

Yes I have a dedicated 20a circuit. For sure a P15 will limit the current capacity but in my system the P15 is showing less then 250 watts load. A P20 would be a better match to the PZ no doubt.
I could actually see a scenario of upgrading to a P20 depending on which amp(s) I go with next if the difference in sound continues to be as noticeable. It was like the P15 helped skip some break-in time and allowed the PZ to deliver more of its magic.
