Are manufacturer AC cables good enough?

How about Auto manufacturers? I’ve seen some pretty mediocre tires come stock, and on higher end cars better rubber. FWIW, Naim who are fairly conservative. Offer their own upgraded power cables and interconnects, their engineers can hear the difference, so do PS Audio, and I’m sure a few others. Power cords that come with equipment are adequate, and if one thinks that’s all that’s needed then fine be happy, but  don’t Be a Cable Cop !

"Whenever two things are different one is of necessity better, the other worse."

Tell that to people who ask to have half scoop of chocolate and half of vanilla. They may have different view. Of necessity, maybe even better.

Those people agree with me 100%. They have decided vanilla and chocolate together is better than vanilla or chocolate. I agree with them. They agree with me.

Now would you like sprinkles or nuts?

Hey Glupson: on your ice cream analogy, those people have tried them both, have eaten both vanilla and chocolate ice cream, and they decided which one they like. I don’t think a vanilla ice cream lover never tried chocolate ice cream before deciding they like vanilla ice cream
