If you read the replies I posted from his emails and his summary, he shows what he measured off the shelve. This was a kit that someone submitted, it is possible, that there may be an issue with the build. Dan wouldn't say that without testing. I think the fair thing to do would get units tested that are built by him and restest.
Or you could send your unit in... this could happen in every test that's disappointing to someone. So until new measurements are posted by a neutral party, I don't buy the 83dB claim, sorry. And note u can buy into 90dB for less than 500 bucks these days.
As far as I know, the unit was purchased preassembled. But maybe that is wrong.
Amir explains his rationale for the measuring protocol in several videos. While personally, I may think driving stuff -on occasion- all the way to clipping for the sake of a uniform protocol is a bit unfair, it is easy to read between the lines, and establish if the measurements apply to your particular intended use case. You can't finetune measurement protocols to the particular area where the equipment measures best, it'd be a long test protocol where you first need to go through a wide iteration to find out the optimal range. It should be up to vendors/designers to say something like "If you submit this to a test protocol, these are the optimal parameters I designed this for..."... but that would narrow down the use case, which of course is not in their best interest if they intend to sell to as many people as possible.
Can you verify? Did you do any listening on this device or is that for mfg that sends units to you?
Well, Dan didn't send it for testing and provided his testing. How many other manufacturers have you seen do this?
It is up to you to establish if this is worth your time, given the fact you seem to be perfectly happy with the one you have.
I can read between the lines, and the shortcomings Amir identified were not relevant for my particular use case - where in fact the equipment performs to a very high (measured) standard, if you read through the testing protocol to the parts that matter for your particular use case.
Same here my Anthem isn't a great measure and I love it. What I don't want to happen to one of the few small retailers that is so nice is people see this and go well that's a POSIt is up to you to establish if this is worth your time, given the fact you seem to be perfectly happy with the one you have.
I am a very happy user of a product Amir slammed and didn't recommend (which is not the case here).
I sent an email to see if he wanted to test, as I had to try out a new Aegir 2, I have never heard that style and figured I would scratch that itch.
I asked the owner but he didn't answer. I don't want to pester him. The tone of his original offer seemed to indicate it was pre-assembled. Otherwise I usually ask for checks and balances to make sure the build is proper.
Testers will always perform their test to a standard - otherwise they would not be able to compare the SUT (system under test). Otherwise their task would be impossible. If someone tells them about corner cases they should test, sometimes they'll willingly do it. I face this in my professional life, where we always have tests performed to a standard by third parties, and sometimes we counter things saying the test protocol should be updated because of new requirements etc etc.Same here my Anthem isn't a great measure and I love it.

Help me understand something if you would. What numbers for a class A/B would get most excited? One user stated that Dan is using an AES standard to show his distortion numbers.
To me the class which an amp operates under is irrelevant. All that matters is the measured performance, including power. For less money one can buy an NC252 amplifier with much better measurements and lots more power. That makes this Akita amp irrelevant.
It's irrelevant from the standpoint of acquiring the best amplifier for the money. It's not irrelevant from the standpoint of learning about electronics and audio equipment by assembling an amplifier for one's self.
DIY is an important part of this hobby and many DIY threads get a great response here.
Maybe I don't get it... but putting together a model plane doesn't make you an aeronautical engineer... and soldering together a system following 1-2-3 directions doesn't turn you into an audio system designer (although based on some of the equipment that's reviewed here, that's not an impediment to design and sell audio products, it seems :-D). There are pretty good books about audio design fundamentals.
I guess you don't get it.
