I take offense to the fact that every single time we have a thread in which someone posts a scientifically provable statement you make a point of belittling them in an obnoxiously condescending manner, citing your own phenomenal experience and dismissing that of anyone that disagrees with you. Yes, you jerk, I have heard both. I recognize that audio is a subjective hobby and that some find the coloration that tube amps produce as pleasing. More power to them. I also recognize that not everyone prefers that coloration which is why I suggested that it's best if the individual curious in the tech were to listen himself.
If you can't end your smug dismissal of anyone with a differing opinion and certainly of those with scientific fact behind them I'll simply ignore your "contributions".
