Do power conditioners help with unwanted hum/noise


If so what are the names of the units that give you the biggest bang for the buck...Thanks

It really depends on what the source of the hum/noise is. You need to define the problem before throwing money at it.

Sometimes they can help. The most graphic illustration I can think of is that I used to have a pair of Martin Logan Prodigy speakers. They had a little blue "ML" logo that lit up on the front when a signal was present; if a signal was not present for a sufficient time, they would actually go into sort of a shutdown mode. But, the little blue lights were always on in my house. Until I got a power conditioner. As soon as I did that, the little blue lights went off. So, there was obvious some kind of line noise impacting the signal path.

Oh yeah, it sounded better too. ;)
Edesilva brings up some valid points, but i'm with Kal on this one. The effectiveness of the power line conditioning in terms of noise & hum will have to do with the source of the noise & hum. If you've got a ground loop, adding a PLC won't do much to cure that. At least, not in most cases. Sean
