It's these sorts of comments that allow companies to keep putting out overpriced gear that measures horribly. Well that, and those willing to needlessly put out thoise amounts of money for a piece of gear are more interested in bragging rights, than actual listening quality.
Price is not an indication of quality and performance. In fact, in some cases as we see, the higher the price becomes, the more poorly it measures. Due to the fact, those spending outrageous money on a component, will tend to make themselves believe it sounds better, when in actuality they are are nowhere near SOTA.
Look how far dac's and speakers have come in the past decade. You can great sounding and measuring gear for under $1k. Topping is just one example of the top measuring dacs.
To say $10k is nowhere near high end is just an elitist comment, which helps no one but the manufacturer of said overpriced products.
As far as measuring $50k plug gear on this website goes, you should ask yourself, why are these pieces of high-priced gear not being sent to Amir for validation? Most of us know why, measurements would most likely show, they don't live up to their hype.
