Firstly, I am not trying to start a war with anyone. This is my opinion and I hope you respect my opinion and I do respect yours.
My whole premise is that more effort could be put into audio equipment power supplies by the manufacturers to save a comsumer money in not having to spend megabucks on expensive aftermarket power cords.
I have no doubt at all that you all hear differences with different power cords. My thing is that if the power supplies were designed properly the need for fancy power cords would cease to exist provided the power cord could provide the proper current.
After a lot of practical experience, I have come to the conclusion that the effects of the following plague audio reproduction in the respect to the deliverence of AC power to audio equipment:
1.The rejection and reduction of internal radio frequency interference (RFI) and noise already present on the mains line.
2.Immunity to and rejection of additional external RFI, EMI (Electro-Magnetic Interference) and noise.
3.Low impedance and high current capacity, so as not to current limit any equipment.
Each of these problems could easily be addressed in the power supply of a piece of gear.
I am an engineer by trade and I have designed and built quite a bit of audio equipment including their power supplies as a hobby. My power supplies are always designed to combat the above. I am also somewhat of a diciple of Nelson Pass and his SUSY or X designs and frequent his forum on DIYaudio.
I have listened to a number of high end power cords but have chosen to build my own. I am always a fan of using the best parts I could (wire, and connectors) to build a power cord just the same as using the best components I could when building an amp or premap or my turntable.
I hope I have answered everyones questions. I don't want to write a book here. Again, I do not dispute that people hear differences. I think those differences can be minimized by better power supply design.
