Need for Power Conditioning??


Hey all,

If one builds a new custom listening room and invests in a serious power system, like Equi=Tech and puts in high quality wall sockets, would one need to use a power conditioner/distribution system like those from Shunyata, Walker, HB Cable Designs, etc??

If someone has clean power coming from the pole, the room is properly grounded, and you have a high quality install, why would someone still need any of the products I listed?? Just curious!!

Cheers,

The power coming from most poles is anything but clean. I use industrial isolation transformers and constant voltage transformers, and they are superior to anything made for audio (anything which I have tried, that is). But, as Cox points out, they growl, so they must be installed outside the music room.
Coxhaus you've got a great setup. I'm sure your one of the few to hear a guitar sing from a digital drive. The isolation should be mandatory-well it is for great sound anyway. I agree with Terry-there is no such thing as clean power from the pole, anywhere. Terry, have you found it better to have the voltage transformers ahead of the isolation transformers, or vice versa?
The power system would be great for filtering out external noise from the power grid. The power conditioner/distibution system would be for isolating your components from one another. Both are potentially useful.
You also want a dedicated run for you listening room only. This reduces "in-home generated noise" contaminaion of your audio-video room.
Every electronic device you use contaminates the mains; your amps dumps noise into the mains that your DAC and pre-amp must consume. They in turn do the same.

Best is to have at least one form of conditioner per audio component. Needn't be an expensive boutique gear. A capacitor-inductor-capacitor filter for each device works magic and makes a huuuuge difference.
