    Re: Cleaning up dirty power...What's your flavor?

    Over the weekend I checked grounding on my amps, moved cables and wires around behind my rack. I got rid of some noise, not all. This week I am going to try and land a new ground rod and maybe a subpanel. Pulled a little 100 amp off a job. I would rather not use anything and clean up what I have with good practices.

    How did you know that your power had problems at the source To the point where you called in your power company? Did you measure it somehow?

    When we bought our home ( ps I live at the beach) we installed a whole house generator,, the electrician and the generator company noticed some odd readings with the ground also found noise on the main line. We have always had some odd static pictures on the TV and hums on our phone line with is provided by the cable company since we moved in it was never right. The cable company said it was a power company problem. So we called our power company, who came out and installed a recording device to monitor the power feed . The next day the started working on a few poles up the road. The power company said it was a faulty transformer ( old age) . They also added another section of ground rod after they megged my ground. Thats it. Nothing magical

    So maybe you were fortunate with your hums and static as a legitimate way to get your power company to come optimize your power. Without serious problems like that, the local power company's not going to come out to help us get out power source to audiophile standards.

    All depends on where you live I would think unless one lives in some high raise or a condo community then all bets are off. .

    Re: Cleaning up dirty power...What's your flavor?

    I have 4 20A dedicated circuits. I use a pair of huge Toroidal transformers (Balanced Power Technologies) for my amps that can provide more instantaneous power than your 20amp wall socket. For my front end I use the Shunyata Research Hydra Triton.You can't get any blacker backgrounds then what I have! Ask Mike!

    Re: Cleaning up dirty power...What's your flavor?

    I seem to have a fair amount of noise coming in on my line as measured by my Entech meter. My topaz isolation transformer takes care of 95% of it for my sources. But it can’t handle my amps: 2 mono Sets and the sub amps from my Avantgarde duo mezzos.

    I have a 20 amp dedicated line for each pair of amps.

    Any suggestions for maybe a small,quiet isolation transformer for each of these dedicated lines?

    I wonder if I should recheck my grounding as well, as noise levels didn’t measure this high a couple of months ago.

    I don't know what topaz you have, but I have a 2.4 KVA unit I was looking to sell. Ir's a pretty robust Transformer for only a few hundred dollars.

    By the way, I would sit this Transformer in the basement next to the panel. I would find that line going to my audio source and put it on the load side of the Transformer down there.
