If the PZ must be plugged into the wall, as per Gryphon, and it doesn’t do anything to the current path, as per Paul Hafner… it would be interesting to understand what is recommended for:
DC blocking when a system needs this kind of thing
Surge and peak protection
I was used to plug my amp directly into the wall socket, so I’m not concerned about that but other components might be a different story.
Oh… to be clear: I’m really impressed by the result after only 3 hours listening! It seems the PZ will become soon a fundamental part of my system, something I cannot live without. Therefore any possible speculation on other correlated arguments… cannot change what I’m hearing! Said with a big smile on my face!
Give it enough time to break in and then consider selling your P15 as well as the Puritan.
IMO early comments regarding the PZ are meaningless, more about self affirmation than anything meaningful, much less actionable. iI find it amusing to say the least.
For DC blocking we are back to a Puritan ahead of the PZ. Most have had the PZ for less time than what would constitute a meaningful break-in and are considering ways to improve on the PZ.
Maybe the PZ is not all that. Most amusing.
The plan is to sell my P15 after I come back from vacation, and use the proceeds to buy Muon Pro.
Puritan will stay since my OLED big screen and B&W Formation bar/bass are using it. No, I do not see a major improvement, but it is better than a Homedepot power strip for sure!
Does DC blocking lower THD? Is DC the carrier of the grunge we hear? Are there in line ac line filters that are available so I don’t have to feel bad about selling my P20? Am I mad?
My thought exactly, but yours had 5 days break-in already. I am the only one who experienced flat SQ on the 2nd and 3rd day which was interesting. But after that SQ was better day by day.
My system is still sounding better without ground wire. It will be interesting when you experience with CAD (I am sure you will later ).
Or just running the PZ into to wall. Personally I would give the PZ time to break in. 1 month would do according to Paul Hafner. Then try your favorite device. I’m in the school with dedicated 20a outlet with the only device plugged in the PZ.
The best answer is whatever sounds best to your ears.
There is a point where PZ gets to what I’ve dubbed “addiction mode” this imo is when the PZ along with your system becomes very difficult to walk away from. Mine is very close! If it keeps getting better what’s next? Ludicrous speed or do we go straight to Plaid?
I thought it through when I decided to sell my P15.
Hopefully the Puritan moves as well.
As I have often stated consolidation and downsizing in a meaningful way is my objective.
The PZ 3.10 should get me there.
FWIW, THD is independent of DC offset on one’s incoming AC.
Just trying to ascertain if my dirty ac can cleaned, and if so, will it help or hinder the overall great results with the PZ.
Fewer boxes mirrors my goal as well. Being exclusively in the digital domain seems to be putting that in reverse. Now whose going to make an audiophile router?
Good point. Until today I have not experienced this level of graininess. I’d also characterize it as a temporal shift within a very narrow bandwidth. The graininess seems to lag ever so slightly the harpsichord plucked notes. Odd, and possibly emphasized by the PZ as it continues to break in. I’ve not heard this on this system previously.
My Trio 15 Classics with the Voxativ PiFe FR drivers do have the upgraded crossover components, Mundorf Silver Gold Oil Caps, Mundorf precision resistors, and precision wound inductors. Once I’m confident the PZ has settled in adding the suggested Dueland JDM silver 0.01 microfarad bypass caps may be a good option. Easy to do on the PAP Xover.
Clearly not. From what I heard at Axpona, I believe it ultimately comes down to the PZ receiving its due regarding a proper break-in as the Gryphon system sounded clean and clear, wart free.
I do feel your pain regarding a 7-10% THD, horrendous. A K-factor pole mount transformer, designed to address the switch mode induced THD may be the answer. It won’t be cheap, but my guess is less than the PZ.
Selection and sizing would require a local power quality analysis, best done as a time averaged data set over a period of time. Instantaneous can be meaningless as distribution voltage fluctuations, especially voltage sags can compund power quality problems. The P15/P20 may provide a general idea of incoming power quality, but the best path is to utilize a profession with a Fluke power quality meter. Contact ComEd, they may be able to provide this service for you, dependent on your current service classification and can advice as to the sensibility of a K-class transformer installation.

You, Al, Luca, Paul, and the rest with oxygen masks can fly a whole lot higher than me! Enjoy!
