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

Ok, this may seem like a silly question to some; many of us know that it takes time for the amplifiers to break in. I have been observing it again and again, with every amp I have or have had in the past. Can the breaking in differences be measured? Like before and after. Before is when it is out of the box brand new, and after, say, 100 hours of listening. 

I've read here on other threads that there's no difference in measurements before and after break-in. Yet, like you, I heard the differences, even during the break-in period. 

On another thread about measurements, I mentioned that I read on a review that despite the different options for selecting filters (on a CDP), they all measured the same on the component. I even cut and pasted the section on it.

 Hmmm? Different filter settings resulting in obvious sound differences yet they all measured the same. Could it be that the analyzer could only "measure" the summing of the signal and not the "flavor" of the settings? 

I never got a cogent answer for that.

worth noting that you’ve got several other fairly prominent measurement focused reviewers out there (atkinson, erin, goldensound) and ASR members have argued, downplayed, & criticized all of them. and who here has a problem with any of these reviewers? i think they do great work.

and i personally don’t think it’s really about objectivity or "science" to some of those asr guys, and i don't think most so-called subjectivists have a problem with an engineering-based critique of a piece of equipment. it's really just about not being a jerk and pretending you have all the answers about hi-fi because you can perform a test tone sweep. 

I am still amazed at the vehemence of the attacks on Amir and his following on this thread. All he is doing is applying scientific criteria to his reviews of audio components. Additionally, he provides extremely valuable insights into craftsmanship that is often sadly lacking in high priced equipment. I doubt if any middle of the road ASR adherent would criticize someone who liked tube components; they would just note that the unit didn't measure up to scientific standards. It may well be that the most accurate sound doesn't sound as attractive as some tube component. Thanks to ASR I discovered class D amplifiers and am hugely delighted with my Purifi amp--to me, the sound is stunning. The site led me to RME and even Topping--the former is a wonderful DAC. People get emotional over the cable business but the bottom line is that the manufacturers make wild claims about their often monstrously expensive products that cannot be substantiated. Skepticism is a good thing, and just because someone gives you a lot of mumbo jumbo about some fanciful thing doesn't mean they are automatically right. To me Amir and ASR in general have demystified a lot of audio myths and I like that, even though he made me feel like an idiot for buying that USB cable. 

I'm still amazed at the hyperbole that ASR adherents use when describing anyone who disagrees with them. Also, the overuse of the term scientific as if it's a charm of sorts and can't be refuted, lest one anger the audio gods.

All the best,
