@falconquest , I've been following the balanced power threads and it seems like the way to go. I don't have the funds to do it now, but I see it in my future. Would be much better than using filters and grounding blocks.
Thanks.
Thanks.
Dedicated Line Noise Filter?
I don’t know if what I’m seeking exists, so I’m asking the experts.
I have 2 dedicated lines installed; one for analogue, one for digital. They originate at a sub-panel off the main circuit box. The sub-panel is connected by the hot lead and has it’s own ground including a second grounding rod. There is a home surge protector installed at the main circuit box.
I have passive conditioning on both lines for the components, yet I’m still hearing noise thru the speakers (from about two feet away). I live in a city and I suppose it could be dirty power from the grid.
Now to my question; is there a noise filter that can be installed at the site of the circuit panels? My electrician offered a surge protector with noise filtering (plus EMI/RFI), but was very expensive. So, is there a device that can be installed upstream to lower the noise floor?
Many thanks.

After much troubleshooting I can confirm that both dedicated lines are extremely quiet. My preamp is emitting a low-level hum (even through a power transformer). Swapping preamps proved that the mains had no noise to speak of. So I will address this issue with the manufacturer, then hopefully move on to some "black-background" listening sessions. Thanks again to all. |
I have a BPT 2.5 Signature Series and my system is dead silent. I just checked U.S. Audio Mart. This is the unit I would have purchased had I been able to find one used. I get your funds situation but this is an excellent buy. http://www.usaudiomart.com/details/649370283-equitech-2rq-20amp-balanced-power-transformer/ Here is the Equi=Tech price list confirming the price of this unit... http://www.equitech.com/purchase/retailprices.html |
