The plc (poweer line conditioner ) that worked for me is the
discontinued PS Audio Quintessence…
From the owner’s manual:
The next position is the Incoming THD measurement. This measures the percent of harmonics
present on the incoming AC line. Typical in a home is between 2% and 5%. Harmonics are
generated by distortions in the AC waveforms, clipped top of the sine wave and added noise. These
The Quintessence can not improve or repair the distorted AC sine wave. Only a Power Plant AC
regenerator can do that. The Quintessence will, in fact, clean anything above 2kHz, including some
The Quintessence Power Center is a state of the art AC
power conditioner producing clean and protected AC
power. The Quintessence Power Center has a revolutionary
new filter inside that cleans the AC power all the way into
the audio frequencies. Before the Quintessence, passive
power conditioners were restricted to 50kHz and above.
Now, with the Quintessence Power Center, cleaning of
noise from the AC line occurs at frequencies down to
2kHz! Clean AC is essential to optimize the performance
of your connected equipment.
The filter employed was a large sized nano crystaline
material developed by Hitachi…
This thing worked very well for me…but was not a regenerator.
Previously I used a Tripp Lite LC1800 voltage stabilizer and condtioner.
The plc aspect didn’t start till well in the mghz range…useless for audio.
Didn’t improve a thing in my system.
Results with plc will vary by manufacturer design and quality of
In all of this plcs will not recreate a clipped ac sine wave and make a new
perfect ac sine wave…that only a regenerator can…this then is the ultimate
ticket for perfect clean ac power 24/7 …
Thinking that my Quintessence could not be bested …years later I acquired a
P5 regenneator…difference was an amazing night - day difference.
Hope this helps…
