Last week I ordered a Pangea Audio P-100 to use with my Musical Fidelity V-LPS. I was very excited about this upgrade since Stereophile raved about how it was such a significant performance upgrade. I was using a Pyramid PS-3KX with the V-LPS for the past 6 months, which was already a great upgrade to the stock wall wart.
I received the unit, swapped everything out and flicked it on. I immediately heard a hum and my heart sank. I thought the whole point of a quality PSU was to get rid of hum. I tried everything to get it to stop humming. I repositioned it, tried different surge protectors, and different interconnects but all to no avail. It still made a hum, even at low volume, no matter what I did.
Although there was a hum, I could see why Stereophile loved this unit. The soundstage got wider, instrument separation improved, and bass tightened up. I debated whether or not to keep the unit regardless of the hum but I just couldn't do it. I returned it to Kraft Street Audio/Amazon today and went back to the Pyramid. The Pyramid's does not hum and performs admirably, especially for the price. I'll stick to this for the time being and maybe save enough money for a better phono stage or invest in the V-PSU II.
I really wanted to love the P-100 but the hum was a deal breaker. Any P-100 owners want to chime in? Perhaps I had a defective unit.
