    Super Quiet Noise Floor

    I was complaining on other forums of my noise issues at my house. For years I blamed my home. Come to find a lot of my issues were my amps. I bought new amps and that made a significant impact. I still had some hum. Not heard at the chair any more. Not unless it was super quiet and I sat and intently listened for it at its worst times. This is way better than it had been, but louder than I wanted.

    Ultrafast and I had just done some work at his house. He told me to run a second circuit dedicated to my amps only. I did as such and what do you know. 2 circuits in my system are better than one. Again my noise floor dropped quite a bit. Now that only hum I heard was when I was right up at a speaker. I could no longer hear anything at my chair. Take away here. Don't listen to anyone tell you how many circuits are best for audio. My belief is your system will tell you. We each have a very unique setup, and unique home environment. What works for one, may not work for another.


    Ultrafast also utilized a few Environmental Potential EP2050. They are a surge suppressor and also suppose to get rid of noise. You can find info on the web and read if interested. Anyhow, I have had it in for 3 days now. I have to put my ear to my speakers to hear any noise now. My system is the quietest it has ever been. It is such a relief to not have an incessant hum heard at my chair. I now get a little unnerved that try as I may to hear hum at my speaker I almost cant. The quality of the input tube actually has more impact on noise now than anything else in my setup.

    KingRex - we are checking boxes, doing things right, it’s working!

    I’m excited to hear these improvements!

    No doubt Rex has a solid electrical foundation, with proper grounding and now all electrical will benefit by adding Environmental Potentials EP 2050, waveform corrector and surge protector.

    This is so good, we are starting a Company!

    Re: Super Quiet Noise Floor

    I have never had any noise issues with my system. Either with a single AC circuit, or the current three circuits. Glad you are making progress as noise drives me crazy. I moved my refrigerator into the garage to get rid of that noise.

    Super Quiet Noise Floor

    Try a pair of nord nc500 mono amps or other class d types just to get a baseline for low noise. You may despise class D but at least it'll get you an idea of how quiet things can be.

    Well if you could hear hum or hiss at the listening chair you clearly had quite a few problems. Glad you're figuring it out.

    Do you provide quotes to get other folks in the Seattle area a better electrical system for their homes too?

    PM Ed about work. I hope Mike does not get upset here. Ed needs to figure out how to get the business info out without breaking forum rules.

    I did put a class D amp in my system. That is part of how I determined a piece of my noise issues was amplifier related. After I got more quiet amps, adding the second circuit definatly cut more noise. The EP2050 has keep remaining noise very low since installing it.

    Watch for a new post by Ultrafast. He did some more ground work and is very happy.

    Ed and I are now Audio-ultra.com
    We have leaned so much about noise. We are looking at scopes now to more quickly isolate problem appliances. And to push utilities to replace failing infastructure when necessary

    Both our systems are very quiet. The more we grow, the more we are seeing. And what we see is most noise is from in your home and from poor wiring. If your home is addressed properly, most of the complaining about dirty utility power is filtered away. That was a pun.

    Re: Super Quiet Noise Floor

    I see you seem to like Square D Panels from reading your other posts. I was wondering if it would be more ideal to have a competitors brand panel that has copper & silver flashed bus bars instead of a standard Square D panel?

    Thanks
