Power Line Conditioners and Regenerators: A Buyer's Guide
A power line conditioner cleans the AC feeding your system, removing electromagnetic and radio-frequency interference so your components work from a quieter foundation and reveal more low-level detail. A regenerator goes further, rebuilding the AC waveform from scratch for stable voltage and minimal distortion. Both lower the system noise floor; the right choice depends on how dirty your mains supply is and what your amplifier needs.
If your system reveals background hash on quiet passages, conditioning is worth investigating. If it already sounds dead quiet, treat it as optional. As with cables, the honest test is whether you hear the difference on your own gear in your own room.

Conditioning Approaches at a Glance
What Does a Power Line Conditioner Actually Do?
It filters interference out of your AC line so the rest of the system starts from clean power. Your mains supply picks up electromagnetic and radio-frequency noise from everything sharing the circuit — chargers, dimmers, fridges, Wi-Fi gear — and that contamination raises the noise floor your components have to work against. A conditioner removes it and, in the better designs, also protects against surges that could damage equipment.
Filtering vs. Regeneration — Which Is Right for Me?
Choose filtering when your mains are reasonably clean and you mainly want to quiet the front end; choose regeneration when the supply is noisy or voltage sags and you want every component fed a clean, stable waveform. Passive filters strip noise from the existing AC wave, whereas regenerators such as the PS Audio PowerPlant series rebuild the wave entirely, correcting voltage and distortion. Regeneration costs more and is the more thorough fix; filtering is the lighter, more affordable step.
Will a Conditioner Choke My Power Amplifier?
A well-designed conditioner or regenerator will not, because it is built to pass instantaneous peak current on demand and often improves amplifier dynamics rather than restricting them. The old worry about current-starving an amp came from undersized or poorly designed units; modern high-quality designs are sized for the job. If you run a large amplifier, we will match you to a unit with the headroom it needs, or recommend feeding the amp directly while conditioning the source components.
Do I Still Need Good Power Cords?
Yes — a conditioner cleans the power, but the AC power cords deliver it, and a weak cord can re-introduce noise or limit current right at the last step. Think of the two as partners: clean power from the conditioner, clean delivery from the cords.
