It was interesting stumbling onto Audio Science Review www.audiosciencereview.com and reading various test results and evaluations of audio gear. The founder and principal tester appears to have a considerable technology and audio background. His evaluations of some well-known manufacturers products, based on his measurements, are not always flattering. It's even more interesting to Google the products and read seemingly glowing reviews. I know the old retort is that great sounding gear might not measure well, but it's interesting to read his opinions. |

Not really. Very few narcissists are. |

Totally incorrect. There was no such flaw. Perhaps you missed Uptone's rebuttal? Perhaps you're referring to something different than I. The original Meanwell energizer was exhibiting "high-impedance leakage" and a wire running from AC to DC output ground was installed. All subsequent models contained that enhancement. I just purchased the updated version directly from them. |

Notice the dates involved. The audioscience post was in August. In September, John Swenson (the designer) acknowledged the observation in September with this post |

The place is vile. He was ousted after an uprising..that may tell you thing, he was even too insufferable for this place. |

Pretending that this doesn't matter is only fooling oneself. Your welcome to your opinion, but I find zero correlation with THD or IMD telling you anything valuable as to how an audio component sounds. You need not present any more logical fallacies. The usual response to a comment like this is that the feedback system found in most amplifying devices cleans that right up. Not so! In order for the feedback to work you need adequate open loop gain at the frequencies you're trying to reject for the feedback to work. Guess what! The open loop gain drops dramatically in most amplifying devices aimed for audio use outside the audio band. So, this rejection mechanism doesn't work. Agree 100%. As does Nelson Pass. Which is why I'm not a fan of op amps which require ~40 db of corrective feedback due to their large open loop gain. Great numbers. Mediocre sound. |
