Who Tried Power Conditioners Over The Years and No Longer Use Them Today, Any Why?

I'm unaware of any solid evidence that power conditioners improve sound in a normal home electric setup. Esse est percipi. 

My Ears are my evidence in my system.   YMMV.

I had one power conditioner and auditioned another.  In my oponion there was little to no improvement from either device.  I deicded to try one more time and purchased the Puritan PSM156 earlier this year.  I was shocked by how much better everything sounded with the Puritan. 

Always been a little skeptical about these types of devices but Purtain, at least in my system, has improved the overall sound quality and I guess either eliminated to dramatically reduced the interference. 

Yup.  My ears provided the solid evidence that the Puritan was getting the job done in my system.

PowerVAR is what I have. Also my strero system is on a dedicated circuit with 2X 30 amp circuits, so basically I can run all of my equipment
