How much power does the UPS need to supply? Does the UPS output a true or stepped sine wave? What is the audible noise level? What is the level of powerline noise on the input and output sides of the UPS?

Regenerators are conceptually very similar to online UPS systems except that there is no battery. They are basically amplifiers designed to output 120V at 60Hz.

A power conditioner with voltage regulation keeps its output at a fixed voltage of 120V for a range of input voltage conditions. There is normally a minimum and maximum voltage within which the regulator can maintain a constant output voltage.

Power conditioners with this feature can turn off their outputs and
hence connected equipment in the event of a potentially damaging and
prolonged under or over voltage condition.

A dedicated line is an electrical circuit used solely for the purpose of supplying power to an audio or video system. No non-AV equipment should be connected to a dedicated line. The line runs back to the main service panel or a sub panel.

Ideally the AC power that feeds our high performance audio, home theater and studio systems would be rock steady – it would not go up or down in voltage depending on the time of the day and it would not get interrupted by storms or accidents.

Lightning* is perhaps the most well known surge event as it is capable of causing catastrophic equipment damage where whole systems are destroyed with one 6000V+ strike.

The exact effect of noise is dependent on the quality of the power supply inside your equipment, but unfortunately there is no relationship between equipment price and power supply performance!
