Well that does kinda tell me you didn't actually try doing what I said above, it's expecially apparent with IEMs since you remove a lot of variables with them.

>Technicalities are acoustic properties that aren't related to subjective aspects such as tuning or timbre. Technicalities cover areas such as soundstage, resolving ability and attack/decay.

There are definitely a few things that needs to be said about this statement:

a) Tuning isn't really a subjective aspect but it's very much objective, you may say that tuning preference is subjective but even that could be argued a bit since there is clearly a trend when it comes to preference among the general population.

b) Technicalities are also very much a subjective criteria (As oratory1990 himself noted) and you often have disagreements when it comes to that aspect even among well known reviewers.

c) As you can see from that comment technicalities in general are very much directly related to tuning since in the end that's pretty much the main aspect you have when it comes to audio transducers (Barring audible levels of nonlinear distortion), the thing is that it's generally kinda hard to quantify what aspects of the tuning makes the difference between a "highly resolving transducer" vs one that just has "good timbre" really.

It can be argued that FR graphs aren't the most accurate compared to how they would actually sound in your ears but again eh, it's also the only thing acoustic engineers have to go by when it comes to tuning their stuff besides listening with their own ears (Which are different from yours too) and of course a test group if said manufacturer is big enough.
