You use a lot of technical terms which makes your post sound official, but you back up none of your claims with specifics on how a "audio PC" solves those issues. There are a few types of power noise (RFI, EMF, switching PS noise feeding back into your house AC (see light dimmers and anything else that uses a switching PS), AC phase and amplitude changes).
Unless a PC has active or passive components in it, or shielding, or twisted wires (canceling common noise), a cable does nothing to clean up the AC power. Also, why hook up a mega bucks PC to house wiring or a mega buck outlet socket. That is nonsense. Its like paving 1 foot of pavement on a street in gold to solve the other 200 miles of pavement full of potholes.
Before spending any $$$ on cables, I would recommend upgrading any components that use a switching supply to ones with a linear supply. I would also invest in a power conditioner. Not an "audiophile" one. A lab grade one used in a testing lab that measures RFI and EMI on customers equipment. Ones with big capacitors and big transformers (preferably toroidal as they tend to add less EMI).
Then for power cable from your power conditioner to your equipment look at ones with enough gauge to carry the current (watts) you need and ones with twisted hot and neutral (unless you power conditioner puts out a balanced AC signal (google it)) and a good overall shield that is grounded on one end only to the ground prong (third pin) on your AC outlet (not to your amp) you do not want any noise left on the cable shield getting anywhere near your amp. Ferrite chokes on either end is not going to hurt, but not really needed after the power conditioner unless you live next to high tension power wires or a radio station tower.
Also keep your PC away from your interconnects or if they must cross have the cables at 90 deg to each other.
Keep your interconnects short and go with longer speaker cables. The signal in your speaker cables are carrying a much higher powered signal which is less susceptible to noise interference.
The aircraft guys know what they are talking about... bad or noisy signals when you are flying are very bad. In your pharma business, talk to your instrument techs about how to maintain high quality Analog input signals to their PLC, DCS, or data acquisition, especially in an industrial environment. Ask one on them if they ever solved a noise problem by changing a power cord. Smile when you ask so they know you are joking.
Enjoy audio, but make good friends with a radio, signal, or low voltage instrumentation electrical engineer if you want to learn how to make your system better based upon scientific principles and not someone trying to make a house payment selling fat PC cables.
One last thing. (At your own risk of course). Pop the cover off your amp or pre-amp and look at the wires coming out of the other side of your IEC plug that you just plugged your $5K cable into. Notice anything special? Nope. Looks just like some wire I could pick up at radioshack.
Have fun all.
