Just opened mine now. Both drivers had "12061" hand engraved on them, the left one had a "2" over that, the right one a "3". Once again I have the feeling I haven't found out anything new about them (and their real age), but to be honest it doesn't really bother me, because they sound fabulous...

  Will take other shots tomorrow.

Quote: Yes, they are titled DT48S, have chromed cups, the grey pad on the headband and are labeled as 25Ω. The pads weren't the original ones though and I don't know how old they are. If I get a matching screwdriver, I could open them up and look whether there's a production date that...

I'm quite happy how my DT48S @25 Ohm (probably not the old Nagra edition) sounds out of my small DAC, so yes, unless I have too much money to spend, I won't bother buying other versions to compare as well.

It would be more effective to use either EQ, mod them a bit (a thin piece of cloth is very good for that) or get headphones with less agressive highs.

Quote: No, they don't unless you buy them in used condition.  

KBI did compare them to a HD800 several times, some other's did as well (just google "DT48 HD800"). They should be similiar, but the problem is that with the roll off on both sides of the frequency graph it's hard to say whether the superiority/equality of the HD800 is real or only faked by...

Umm, yeah. Have you at least tried them out for some time or are you only rambling about stuff you haven't experienced yourself yet?

Obviously my argumentation was about that when headphone graphs after a certain part goes wild (upper highs especially), you can't really use that part for prediction of a headphones treble sound. If I suspect a bass roll off, a not so far going frequency graph will neither prove or make my...

Uhmm, yeah, the FF graph doesn't go below 200 Hz.

If his amp has an output impedance of 120Ω, it could indeed bend the frequency graph to a more neutral curve. You can simulate that by plugging an 120Ω adaptor between your amp (with around 0Ω output impedance of course) and the DT48.   Using low impedance outputs however makes them sound...

The DT48 seem to be tuned to a free field response in contrast to many other headphones which are tuned to diffuse field response. Because free field sound (like things played live outside) doesn't have much bass or highs, it seems to match to their treble and lows rolling off early. This would...

Well, the TripleFi 10 is one of the few exceptions of reosanably priced BA bases IEMs with heavy bass emphasis due to the three drivers used. The Fischer DBA-02 (or Brainwavz B2) tries to accomplish the same with two drivers, but doesn't really succeed.   So I wouldn't put them in the same...

I'd rather call the TripleFi 10 the polar opposite to the DT48. Unfortunately I can't compare them directly right now, but these IEMs definitely rival them in terms of speed, detail and preciseness.   People who know a little bit more about BA based in-ears, should know their further...
