"But if you have never tried it any other way, how could you possibly know any of the stuff some of us are speaking about?"
I've never tried jumping off a building, but I've got faith in how the physics would play out:).
If it is relevant, I, and by his comments, poor maligned and mistreated Rwwear have done all the classical things to establish and maintain a hard buss to breaker/fuse panel and we've both tried power cords from some of the big name company's. In honesty though the most expensive power cord I've had in my system was 600 srp so the case could be made that I haven't tried a 'real' power cord.
I bought them (only three in total actually, another argument could be made that I'd need to try 5 or 10) after eating up audio dealers valuable time and effort on equipment auditions that didn't motivate me to purchase, and it sounds like Rw (shorthand) gets them for free.
I don't think there is any merit to your position on the benefit of high cost pc's and I accept that you don't find merit in mine either.
Data in hand is where things will be interesting. If it can be proven that pc's can fix problems I have some industrial equipment applications that I need to talk to the pc manufacturers about.
