What mod?
it is not a mod! not yet.
As explained before, I do not have access to testing gear to keep measurement scientists such as yourself happy with colourful graphs.
Perhaps, an XC-21 owner with measuring gear, can supply one, just wait and see.
This is merely a first step experiment, removing one screw out of four is neither difficult nor irreversible, nor a mod.
I am just investigating to see if others can verify it.
it is a 30 second experiment + some auditioning.
Frankly, arguing with you, whom I believe does not even have an XC-21, is wasting everybody's time.
So you voiced your objection, now you need a graph or else!?
Once again, there is no mod - if results come in positive, i.e. others confirm a change, then we sit down and think of a mod. or forget about it.
BTW, measuring gear for headphone FR are mostly unreliable, as tiny gaps here or there would influence the bass response.
Just check the web. for this very headphones, FR graphs from different sources do not all agree, specially at bass.
You go ahead and EQ the living daylight out of yours, let me foolishly tamper with mine.
I am gonna stop arguing, you are correct, this is a waste of time.
