I understand him, if an engineer has a hobby he is not an engineer anymore, despite of diploma, knowledge and experience.

I.e. in order to continue being engineers we have to hate our projects.

I was very surprised when reading the article, and especially the discussion. Stereophile lost a lot of its credit, to me. Which is not important, of course.

JA's comments on Class D may or may not be correct, but in this case he was not attacking DIYers but being attacked by a DIYer.

Mikey, "prince of price-no-limit" as he was once named in a letter to the editor, completely tanked the ML Class D monoblocks in the last issue. Those are some $50,000 amps. So, there is the occasional negative review, in between hundreds of 'likes.'

In this case, it would be fair to say the speaker measures woefully and is a flawed design to begin with. But the personal attacks on JA are not fair, IMO. Which other magazine puts up any measurements at all? Maybe SoundStage. The Stereophile library of measurements in the largest that I know and there is enough there for the person in-the-know to figure out how the equipment is going to sound.

I don’t see a problem with that. It is to be expected.
Excersizing a hobby is an intentional educational process. We are all into this for to gradually build some knowledge, by trial and error, by studying and breadboarding, by digesting and bench testing members knowledge given here and elsewhere on good will.
Amateur, is a qualitative adjective (the lover of the craft), denoting intentions mostly.
Knowledge and capabilities vary a lot. Much more than among people involved professionally with the subject of this hobby.
On the other hand, professionally involved people may have some vested interests to defend (commercial products, brand name, fame). Thanks God, this is not always so.

The monster that we all have to fight against, is the size of our ego.

Reviewers and editors of Hi-End magazines have to function in a gray zone (“Hi-End” zone)

What's wrong with the Kantor simulated load?

Write slowly, as if you're writing for a non-engineer. Which, in this case, you are.

Why I should be motivated to repeat it once more?

The only reasonable reason to be opposed to that measurement is simply that one's invested in crappy amps (glorified lightbulbs, etc.) and the measurement shows that they're low-fidelity devices compared to modern amps.

Let's not turn this into another stupid "Transistors vs Tubes" debate, shall we?
