Audio Science Review = "The better the measurement, the better the sound" philosophy

No Faraday cage. Those are used for EMC testing. None of you use your stereo gear inside such a cage so I don’t see why I should test them that way.

Cabling for XLR is Mogami Gold. For RCA, I use Amazon Basics. No power conditioning is used or needed. I have tested a ton of these and either do nothing, or impair performance. I do have a LAB AC generator that I use for special testing. Ditto for DC lab generator."

Thanks Amir for response! I can ignore your test results now!

Well that was anti-climatic! :) FYI I own high-end cables like Transparent Audio, Audioquest, etc. that when needed, I use. Usually to deter excuses like you made above. But no, my measurement gear didn’t come with such cables, nor is there a single recommendation to use such.

Do you have any data that measurements are impacted by the things you mention? Or is it just gut anxiety?

@cd318 , I honestly appreciate the comment. Perhaps some who are reading this mess will take it to heart. Quite evident, many will not. Some will even resort to inventing a fantasy life in order to feel superior though I cannot fathom what end goal they have in mind? Everyone seems to feel they have to be in a "camp" these days, even if it is not in their best interests, or anyone else’s for that matter. We used to hold everyone to account, now people just pick a side and turn off part of their brain.

Amir, your equipment and tests are “too ancient” and missing novel micro-dynamics, transient, noise and more important performance metrics High volume manufacturing data is missing in your tests as well. 

Too ancient?  What is not too ancient if you don't mind listing?

For now, my AP has a noise floor that is low enough to produce signal to noise ratio as high as 130 dB: 

*Best case* dynamic range of our hearing system is 115 dB (limited by max SPL and noise level of the auditory system).  With 130 dB like above, we have ample headroom.

Transients are trivial to measure and I show them all the time to satisfy people even though they have so little meaning as far as fidelity.

As to "high volume manufacturing," that is not my job. It is manufacturer's job.  BTW, such testing usually uses (an obsolete) audio analyzer with "go/no go." Precision is not required there although would be appreciated if it existed.

My job is to determine performance of an audio device.  Not its reliability. No reviewer can give you that data. The fact that you think my equipment is "obsolete" to do that and that I am supposed to do such testing makes my head spin!  

@amir_asr "I have reviewed 1,300 products” in not authorized/certified LAB? WOW

what is your background, engineering degree etc?

disclosure: I am experienced analog circuit design engineer, currently working at major US corporation 

Good deal.  Please list the audio measurement gear you use and some of the data produced by it.  And once there, please explain why you measure at all as some folks here seem to not like them at all.
