Paul, no doubt this is not going to be a popular post, but for the benefit of PS Audio and it’s community….
Your video of measuring the P12 comes across as a complete Mickey Mouse operations. Seriously. You had a RIGOL MSO2102A Digital Oscilloscope sitting right there on Bob’s shelf for goodness sake, why not use that??
I’d really like to know why so much AC line noise passes right through the P12 - this isn’t about Amir’s measurements, I’ve experienced it first hand myself when a noisy cell phone charger plugged in elsewhere had an audible impact to my audio equipment which was powered by a P10.
Is the P12 really a full AC-to-DC-to-AC regenerator, or just partial?
