But a null test doesn’t help you forget “ they both sound a little different” so the test is saying ‘the one on the left is closer based on the null’ and your ears are telling you ‘yea, but they both are a little off’. So the test result hasn’t solved any real world problem, it only provided a quantum distinction. A real world problem is when your ears tell you something is not right.
If you get two competing products to be absolutely equal in null tests the consumer immediately moves to the next unchecked box on their list.
And each individual prospective buyer has his list in a different order. Color, weight, cost, etc, etc,
So the brilliant mind creating the ‘best’ code to copy a real amp is champion of the accuracy contest yet they only are providing a fraction of what matters most.
The leader of the team developing the product has to be the champion of deciding what is ‘good enough’ to check the most boxes and know which boxes are near the top of most lists!
That is the magic. Get the consumer to say ‘ Ok, product B has good enough accuracy to look at other boxes on my list…
Accuracy is only paramount until it reaches a level of causing enough listeners to say ‘that’s good enough’ then it is no more important than ‘how much does it weigh’.
Don’t believe me? Go ask Gasp100 or a thousand other discriminating gear flippers!
