After replacing the IO card, the situation is still the same.
Is there any similar situation here? Or can I say PS Audio is not compatible to some brands of equipment?
Any chance you can send me an email with the unit’s serial number? This will help me a lot. jamesh@psaudio.com
Hello laidick!
I have a P15 and I have the “Dee*” also but I got less of it after I removed a QRT Qk1 and a Supra MD01-16-EU so my suggestion would bee: Take away everything that can affect your AC-power in any way because it seems that the regenerators are very sensitive on what’s going on with the AC around them.
Dee* = My Dee isn’t a Dee but more of a “Bruuum”, like it’s from a “vibrating transformer”.
Don’t know if it’s the same kind of sound we mean but I guess it is since I can’t think that there are that many different sounds a AC regenerator can produce.
Hello Birger,
Thanks for your suggestion, however ,a regenerator supposed to clean the AC, but now it’s impacted by the downstream device… does it make sense?
What was the source of this P12 noise issue? How did it get resolved?
Thank you!
My P3 has a hum. I emailed with PS about it, and since it’s only audible from 3-4 feet away, and I sit 10 feet away, I kept it. The tech I emailed with encouraged me to keep it, since I wouldn’t get the advantages of the p3 if I took it out.
I recall they thought it was the dimmer switch nasties.
I had an electrician come out to see about getting the outlet on its own circuit and it was just too convoluted for something I can’t hear from listening position.
At some point in time, anything with a transformer in my rack was humming, be it a toroidal, or a rectangular one. That included P15 regnerator, Plixir, and HDPlex linear power supplies which were connected to the mains. Eventually, hum disappeared! It could be the much higher than normal voltage I was getting is back to normal
