I have a P15 and a TriField EM100 noise meter. If I plug the EM100 into the same duplex outlet as my P15 it reports a noise level of ~ 700. If I then take the EM100 and plug it into one of the outlets on my P15 I see the same noise figure. If I power off the P15 while the EM100 is plugged into one of its outlets the noise disappears. Question: is there a type of noise that can flow through the P15? Or, could my PS15 be broken?

Welcome

How does your system sound with and without the P15?

What is your THD% in and out? How hard are you pushing your P15?

THD% In: 4.1% THD% Out: .1%

I have four Benchmark AHB2 amps, a Linkwitz LX521.4 electronic crossover and an EMM Labs DAC connected to the P15. The noise is present on the EM100 meter without any equipment connected to the P15.
