@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. The chart in my profile is generated so an installer can show a customer the before and after (actual). The db and hz legends aren’t in that chart. They are in the PC software when you customize the curves before I save and upload them to my processor though. You must have thought I was using the $20 app or some other type of software. For the Denon receiver you posted about you can get a license for the upgrade for that unit at the Microsoft store. As for your comments about Audyssey it is a shame that you haven’t gotten to try the update yet for your Denon receiver. See: and

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. My systems are shown under my UserID |
@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.
