@bigtwin - I took the negative approach because it's hard know if the improvement is a result of truly being real or if it's just different colored by expectation bias. If someone paid for a product that they expected to be better and found that it wasn't, it seems like expectation bias would not be a factor as the result was the opposite of what was expected.
Ideally, I was looking for responses that said I had a $1000 component and then purchased a $3000 component and found that it wasn't an improvement.
