Best kept secret in AC line filtering conditioning

I like the concept of this grounding unit. The alternative is to use one of the mega-expensive grounding boxes which create a star-ground in a mix of earth and minerals.

Be aware that the Puritan 156 has filters on every outlet and may not work well with power amps (and integrateds) because of "current-starving" under dynamic conditions. Also, the 156 uses gas discharge tubes for surge suppression. The problem here is that GDTs take several microseconds for the gas to ionize and let-through voltages in this interval can be very high.

IME, any power conditioner using filters to shun the AC noise and fluctuations is a compromise. Not only filters restrict dynamics, they also ‘color’ the sound of your system. Some may prefer this coloration (some may call it fine tuning of AC) but you’re not hearing what you’re system is truly capable of when it’s masked with such colorations.

The simplest and arguably the most effective way of AC power conditioning is by way of using a balanced isolation transformer for your system, where everything is plugged into such device, including your amps.

No loss in dynamics with two monster SS amplifiers used on the 156. No speculation here, but actual experience. One is a pure Class A 60/watts per channel by Clayton and the other the #8 Coda powerhouse amp. Both sounded better plugged into the 156. No loss in dynamics whatsoever.

These units do not limit current as advertised.
