One purpose of the power conditioner is to have all of your AC receptacles terminated in the same place to avoid ground loops. The high current ones designated for power amps primarily, dispense with filtering other than surge protection to keep the AC line's impedance low. Typically, the multitude of other AC receptacles on the power conditioner are labeled as to their intended purpose and you should choose the one labeled as such for your preamp.

I believe it all depends on why you use a power conditioner and exactly which power conditioner you are using. With that said if all you are only concerned with is how the preamp sounds you have to try the preamp out of your power conditioner vs your AC receptacle and decide for yourself which you prefer. Your system as well as your physical location and power coming into your home will vary from other peoples systems. In my system a good 3/M power cord connected to an AC outlet would not create a problem. |
Short after conditioner. Reasoning: Noise pickup. A good conditioner removes audible noise and EMI/RFI as well from the AC signal. However this output is not guaranteed to stay clean. To ensure the signal stays clean you want a short and shielded power cord after the conditioner. The longer that cord the higher the chances of noise pickup. Same reason why I recommend not putting in noise polluting devices after the conditioner. This means PC's, network power supplies, etc. |
@erik_squires Thank you. Will do. I ask only because manual mentions "wall plug," implying mfr wants user to treat line stage like an amp. |
