Is Hifiman overrated?

It is common to hear and read that Hifiman is technically far above other brands in the same price range... that it sounds very good for the price. It is like a "mantra" just like the fact that they are not usually "well built" products.

That in the sub250€ range the Hifiman He400se is the best there is, in the sub600€ range the Ananda Nano is the best there is and in the sub1000€ range the Arya Stealth is the best there is. Of course if you want something top the HE1K series is the best under 2000€...

There is a "tendency to discredit" other brands that have top products such as Sennhesier, Ollo Audio, Sivga, Meze, Audeze...

What do you think? Do you think Hifiman dominates the market or is there a product that can be better?
