After Chu's post on Nousaine's story I've been doing a lot of reading on the topic (thanks for the links TimMc) I find it fascinating but some parts are troubling.
Nousaines "legend" number one is:
.1/ Fancy parts improve sound (capacitor dielectric, DACs, etc).
Aren't audio components only equal the sum of their parts? Is he saying Burr Brown DACs aren't capable of anything better than DACs you'd find on a $200 receiver or DVD player?
Power conditioners is one of his ten "audio lies". In it he quotes a Bryston manual that dispenses with the notion of power conditioning. Nousaine says this is how all more or less well designed equipment should be run.
Interested in the other side of the story I found this review on a Furman Power Conditioner on Secrets of Home Theater website. The writer claims of the Power Conditioner:
"...with the IT-Ref, a very thin veil that I did not know had been there, was lifted. The clarity was now like a crystal goblet that was squeaky clean. I could hear the rosin on the violin strings as if I were playing the instrument myself."
I am no electrical engineer but I thought AC into a power supply that includes a transformer is on an isolated circuit than the DC voltages being distributed from that power supply. I don't believe that noise or hum from the AC could be anywhere in the circuitry unless you had some grounding issues. Please correct me if I'm wrong. That doesn't include any inductance related noise which could theoretically afflict one of the aforementioned DC voltages at any point in the ciruit. But the component that brought the AC voltage to the power supply can do nothing to guard against this, maybe some aluminum insulation could help.
Then the review goes on to talk about this little gremlin I didn't even know existed.
“backwash noise (each component produces back EMF) from passing backward through the power cord of each component and getting into the power cords of the other components plugged into that same socket.”
I know I've got a lot to learn, but I think I smell a con
