What kind of THD in and out are you getting?

I have some questions! When some outlets are set to always on. Is the equipment behind stil protected when the P5 is switched off? against spikes and that sort of noise? Or is it recommended to switch off the outlet for the PWD?

Unless you turn the P5 off from the switch on the back, it is still on and protecting the connected devices. (I think) :wink:

Yes, indeed it is!

@nordicbob, good to hear someone else is liking the Tungsten power cords! What "bullet" are you using. In my system and my ears, the silver sounds the best.

Did you hear about the mod that is available to the MPC? Its supposed to surpass the SR Gallileo MPC for only a fraction of the price. I am going to give it a shot. Let me know if you are interested.

By the way, I am going to give some conditioning some consideration. The Audience looks nice. Too bad PS Audio doesnt make this kind of product, aside from whats available with the Powerbase.


I use the silver bullets mostly, but have not experimented very much among the 3 bullet options. I have not heard of the newest MPC mod. I haven't yet tried the PS Power base or the SR equivalent.

If you can get your hands on a PS Audio AC-12 power cord, you might just find that it is a very excellent sounding power cord for the price including more expensive models from other brands. It does not require active shielding like that of the SR either, but the AC-12 is a bit more difficult to manipulate in tight spaces due to being less flexible than some other power cords.

Good luck.

My PPP with Pass Labs x1, x250 and PWD plugged in:



THD out is never less than 0.4% (I think it’s pretty much standard for PPP)

THD in is 1.7%



Update: just checked again: 2.2% in, 0.5% out

Not sure how relevant this is but my THD out has creeped up from 0.4% to 0.5% over the last few days. I havent changed anything in my system and the THD IN has remained consistent at 4.0-4.5%. Just curious on why the THD OUT would suddenly change.

There are many factors, such as the frequency and form of distortion on the input, voltage v. distortion products, etc. I would not take the readout too seriously as it is a general guideline, not a precise measurement tool.



Lately it has been interesting to watch how the incoming voltage drops as the day goes on. It is very hot here and the grid gets loaded down with cooling demands as the day gets hotter. THD increases as well. Right now, incoming voltage is 119.6. It will drop to 114 or so within five hours.

It’s one of the reasons we even put the THD meter and oscilloscope on modern Power Plants. Since the Power Plant’s really the only device out there that can actually do something about the incoming distortion, it’s instructive for many of us to watch the goings on of the line.



Do remember, however, that as cool as the metering system is it isn’t an HP or Tektronix level analyzer, so it’ll drift a bit on its own - which may or may not be relevant to what’s really happening.

While listening to Jill Barber at moderate level.
