I just acquired a new piece. Not able to hear it prior. Had to make a decision without hearing. I did that based on experience with similar gear what I read + my own personal assessment of what could fit the bill. Bought from a vendor with a very good return policy since yes you never know for sure until you hear or try.
I consider the whole measure versus listen argument just a bunch of gaslighting. Sometimes you can’t hear first so you have to decide based on other things like the facts about how a product is advertised to perform and how it actually does. Specs are good for helping make decisions about what to listen to. Measurements are supplemental pieces of info that can help but only if applied properly which takes some degree of knowledge. Which is why as I said we all use the tools available to us to decide. Obviously our own ears are the ultimate test. Just ignore fanatics where ever they might pop up.
