Perceived value of Class D amplifiers. Are we being swindled?

How much are we influenced by perceived value and well-known name brands? I am specifically referring to Class D amplifiers.

Buying an amplifier with all the bells and whistles from a known brand equals dollars.
Buying an amplifier with all the bells and whistles from an unknown brand usually much less dollars.

I have seen many products being sold in the Class D domain, but what astounds me, is the enormous price variance say between a Hypex or Nad amp and a fairly respectable "no-name" brand. Do they really use such special components, or are they just trading on hype?

.. to me it seems some well-known brands have jumped on the inexpensive bandwagon to market their wares for a huge profit.
