@devinplombier I agree, Owens Corning has to pay to use the panther. You think Amir is paying to use the panther, I doubt it.
The Audio Science Review (ASR) approach to reviewing wines.
Imagine doing a wine review as follows - samples of wines are assessed by a reviewer who measures multiple variables including light transmission, specific gravity, residual sugar, salinity, boiling point etc. These tests are repeated while playing test tones through the samples at different frequencies.
The results are compiled and the winner selected based on those measurements and the reviewer concludes that the other wines can't possibly be as good based on their measured results.
At no point does the reviewer assess the bouquet of the wine nor taste it. He relies on the science of measured results and not the decidedly unscientific subjective experience of smell and taste.
That is the ASR approach to audio - drinking Kool Aid, not wine.

@mdalton +1 I suggest it is not just gear that is susceptible to effects of noise or responsible for generating noise, but also interactions between low and high current cables (AND THEIR CONNECTORS) that are operating in close proximity to each other and may create distortion, slight changes in timing or actual signal loss. Until everything is hooked up together, you really don’t know what you got. kn |
The subject of ground loops is IMO under-appreciated in the audiophile community. There's nothing mysterious going on, it's just physics. But it can be challenging if not confusing to learn and apply. Sorting out fiction from fact may be an issue for the layperson as well. Bill Whitlock has put out some of the most accurate and digestible material on this topic. Search "Bill Whitlock ground loops" and you'll find at least a few freely available papers and powerpoint decks he has authored. It's well worth having at least a basic knowledge of safety grounding ("earthing") and how it relates to noise in audio systems. First and foremost to keep yourself and others safe with a proper installation, but also to address noise issues effectively. |
