Interesting video. Okay, then what good surge protector would you suggest if I don't need to "condition"?
It helps to have an electronic background to understand the need for power conditioning. Take a look at the inside of your
Luxman amp here. That is a very high end amp with quality engineering and components. It contains a large, very well regulated power supply. Your line voltage in your house could fluctuate by +/- 5 volts or more and your amp would not even blink an eye. Do you believe that Luxman would charge $10k for an amp that can not handle minor line voltage fluctuations? ... Me neither. All modern electronics can handle voltage fluctuations at the line and power conditioners and protectors make no audible difference.
Expensive power conditioning for home audio is usually wasted money. If you are concerned about surges damaging your equipment, the APC and Tripp-lite brands get the job done, but you need to match the rated power output to your equipment. Downside is that those UPS brands don't look great. For home audio power conditioning you are paying a lot of money for aesthetics, but that can be an important consideration for some if you can't hide the UPS somewhere.
Most UPS models offer surge protection and battery backup power for power failures. The better ones also offer power conditioning as well. This should be a consideration in rural areas or in large cities where brown outs can occur as it will boost the voltage back up to standard levels.
The Niagara 1200 only has surge protection and noise filtering. There is no battery backup power, hence limited line conditioning, and how noise filtering on an AC line improves the output on an amp is rather questionable. It's basically a $1000 surge protector. A UPS with line conditioning offers more benefits for a lot less money.
If you are only concerned about surges, there are surge protectors that wire directly into your breaker panel with the benefit of protecting the entire house.
