Clean AC power


The power to my house comes from the pole on the road, then underground to a large box that I assume is a transformer. This supplies power to my house only: there are no other houses within 1000’. Does this mean that I am getting very clean power?

@nonoise,

Thanks. The improvements you report are just what I'm wishing for. Was hesitating on regenerators, with PS Audio's entry-level being double the price of the Audioquest. Believe I will start just where you did and, with luck, maybe need look no further.

Dirty power = Distortion (noise) comes from 3 primary sources:

1) The utility company – coming into the house circuit breaker panel.

2) Appliances within the house – eg: TV’s, computers, fluorescent lighting, refrigerators, HVAC, hair-dryers, etc.

See: Jea48’s post above

3) The audio components themselves – especially, the digital ones.

Each digital component – modem, router, streamer, bridge, DAC, etc – regurgitates noise back into the audio circuit – as well as throughout the house – and visa versa. Eventually, this noise creates distortion in the audio signal.

The only measurement gauges I own are my ears. The differences can be clearly heard, and are quite striking.

^^^Exactly.

If ’something’ seems off when listening to music - such as a harsh vocal or a ringing piano note or a strident violin  - ask yourself:

Would that ’something’ be allowed on that recording:

- By the recording engineer?

- By the mastering engineer?

- By the record producer?

- By the record label?

- By the recording artist?

Probably not. There’s a good likelihood that dirty power is the culprit. Its causing distortions that shouldn’t be there.



I also use Chang Lightspeed gear, I think the model is 6400.  It works well for my system.  I have read some negative comments about Chang's components some time back, but it seems to work well in my experience.
Everything makes a difference. My electronics allow the user to turn off the displays while in operation. Things always sound better with the displays off. It is the same type of noise reduction being discussed here.

I know that there are a zillion causes of electrical noise within the home. I'd like to know --just out of curiosity--what effect on the mains power the following have:

Step-down transformer feeding my house. It is at the end of the line, no other house being supplied. Does the transformer by nature clean up the power?

All audio equipment on a dedicated circuit and single heavy duty outlet. I suspect that the outlet is only better than a standard one in safety specs.

I cleaned up and reseated the hot wire coming from the breaker in the panel. I also removed a fair amount of grunge on the breaker clip. Don't know if this had any audible effect.

I tried a 1-to-1 transformer to feed all the front-end electronics. It was a fairly cheap unit but rated sufficiently. Can't say I herd any difference.

Any insights on these measures?
