Symptoms of UN-CLEAN power

When talking about CLEAN POWER, what SYMPTOMS or effects are caused by DIRTY or UN-CLEAN power? 


Consider that the power being sent to your speakers, is the AC coming from the wall. It gets adjusted by the transformer, rectified, filtered and passed through the output transistors.

Ideally, the filtration inside the components is such that no noise gets through. However, not always the case.

Any junk that makes its way through, gets amplified with everything else and mess up what is being amplified. One of the reasons systems sound better/worse on some days.

And, it will effect the sound as outlined by @steakster 

1. Excessive brightness 

2. Over pronounced sibilants

3. Strain in the system and the sound doesn’t come out with ease

4. Generally speaking harsher sounding music 


these are all symptoms of when my power gets dirty (between 6pm and 9pm)

After 9pm gets better and especially after midnight it sounds phenomenal night and day difference 


Why do you ask?

Two houses ago, I bought a good power conditioner because I thought I had bad power. It did some, but. Then I moved to the country and my system opened up like I had just bought a brand new everything! Now I’m back in the city and in the evenings, my system sounds harsh at louder levels. Sax and some electric guitars just drill into my head! So the other day I ordered a Entech Powerline noise analyzer. I haven’t received it yet, but I am interested to see what it does.

If you use a power conditioner that offers balanced power it will eliminate noisy AC. Just do a search online. One source is the Equi-Tech website. Once you understand what it does you won’t go back.
