I have this approach to Line Conditioners:

a) Where there is a genuine need, significant fluctuation in voltage, or a lot of noise on a line due to shared equipment, motors, various industrial applications, many VFDs or other devices, Line Conditioners serve a genuine need. These are generally predictable applications in any case.

b) The nearest electrical source to me is approximately 30 miles away, but most of the power we use comes from Limerick, PA (Nuke), or the wind-farm in Columbia County, PA. So, between 30 and 100 miles as the crow flies. Via miles and miles and miles of aluminum and copper. Transformed four (4) times until it arrives at our house at a reasonably steady 118 VAC at the wallplate. Most of the items I operate have decent power-supplies, and can tolerate a certain amount of sag and a certain amount of 'normal' noise. A line conditioner would be redundant.

If that changes, I will invest in one.


Agreed. In my decades as a pro sound engineer where I plugged in the
recording or PA gear into whatever AC was available, I found that using
power conditioners eliminated a lot of problems.

For home usage? Well, if you have problematic AC you only have to fix
it once (as opposed to fixing it for every gig) and maybe a power
conditioner is the right approach.

If not, it's like installing a sump pump in the basement when your
basement never takes on water. It might make you feel better, but it's
basically a waste of money.
