I bought a P10 about a month ago, and am very, very happy and amazed by how it improves my system. There is one interaction with my system that I am asking about not as a complaint, but more out of curiosity. I have a computer front end (a homebuilt Zuma, for those familiar with Chris Connaker’s design on Computer Audiophile). it is a wonderful music source, but has one major drawback — it spits back electronic noise big-time (RFI or EMI, I don’t know) back into my home’s wiring and is picked up by the amp. I can actually here the buzz it creates being modulated as I scroll on the computer’s screen!
Fortunately, long before the P10 came on the scene, that issue was solved. I have an outboard battery Black Lightning power supply by Red Wine Audio. When the switch for the supply is in “charge” mode, my system is still drawing power from the battery but still susceptible to the AC grunge as it charges the battery – I can hear it. But when I flick the charger off, the AC is physically disconnected from my system, which is then on pure battery, and it is dead quiet.
Now, finally, here is my question. My entire system, except the computer, is plugged into the P10. The P10 is plugged into a dedicated 20 amp line. Unless the Red Wine power supply is in pure battery mode, the AC noise is still getting thru to my amp. I don’t understand how this can happen, given that the AC signal, grunge and all, is being broken down and regenerated. ??? Thanks in advance. – David
