Good read: why comparing specifications is pointless


 

“ … Bitrates, sampling rates, bit sizes, wattages, amplifier classes…. as an audio enthusiast, there are countless specifications to compare. But it is – virtually – all meaningless. Why? Because the specifications that matter are not reported ánd because every manufacturer measures differently. let’s explain that...”

It is a good read, but also an advertisement for there own measurement 'skills'. The problem is a lack of standards in specs and measurement methods between companies and reviewers. Comparing specs can be usefull. You don't combine for example a SET amp with an Apogee speaker. Specs, like wattage or sensitivity matter, to name a few. So I don't agree with the author that is pointless to compare.

The Alpha Audio guys are just starting with measuring, and are trying to learn something. That is always a good thing in audio. It is journey for all of us.

That must be it. To me, it just looks like fun with charts. I used to use charts to understand the performance of an organization. I’d find correlations then dig down to the cause and find it had nothing to do with the organization, but some the accounting system’s allocation mechanism. I found all sorts of correlations that turned out meaningless. In chemical and radioactive abundances in a previous career where they were interesting but useless as a predictor.

@cleeds @ghdprentice @kota1 you all nailed it and are calling a spade a ♠️.

I have never been on the ASR site but have seen the musings of Amir’s followers, and that told me enough. Watched on YouTube video of Amir’s and that was enough for me.

@amir_asr indeed, all the stuff you posted about Audyssey is for the consumer version with the $20 paid app. The version I use has a different license (around $200), a calibrated microphone with a serial number that gets linked to that license, and software for PC. 

I have had the Pro version for some 15 years.  Everything I told you applies to it.  You must use the editor to create a proper target curve.  And learn to measure yourself to understand what it is really doing. 

The fact that you post that output thinking your room has that kind of flat response shows that you have no idea what you are doing.  All you did was run some automated calibration and blindly convinced yourself it must be perfect now.  Instead of posting here, learn to measure your room. If you don't know how, I have written a tutorial on Room EQ Wizard:

Until then, you have NOT post a single measurement of your room response.  None.  Come back when you have one.

How about you go and read a review on ASR and watch a video or two before forming an opinion?  They will be devoid of this kind of bickering I am responding to.
