You and my ex-wife may be right, but I am at peace with myself. I'm aware I have many faults and much to learn.
Never said you were stupid; you are obviously very intelligent and may well be smarter than me.
Never commented on sound quality. Simply stated that any cable that carries an Alternating current signal can't be directional. I stand by that statement. The connectors may only fit one way, that's a mechanical thing, not electrical.
I hold 3 degrees in science, and what you're doing ain't science!
The Scientific method requires:
1. Formulation of a theory
2. BLIND testing of the theory (something audiophiles never agree to)
3. Obtaining Quantifiable, repeatable results (not subjective or observations)
4, Publication of your methods and results
5. Review by your peers (i.e. other scientists need to be able to repeat your results)
I'm done. Wasted too much time trying to convince a true believer. I guess I'm not that bright after all.
