So I finally decided to remove the dust on my DT48A

and had a listen this week end. I am now using an Audio GD NFB-28 for convenience. I immediately felt home, with this speed, attack and dynamic that I really enjoyed. Details and soundstage imaging were really neat to me. However, I have also been surprised to notice some slight sibilances especially with female vocals on the DT48A. That is not something I remembered. It confirmed my suspicion that the DT48 can be very picky with amplification matching. I had trully great results, very musical, out of the Graham Slee Solo Ultralinear.
I am now looking for a good sounding all purpose headphone, for casual listening, be it either music (80%) or movies (20%). Obviously, the DT48 won't be suitable for this with its weak low end. I ordered the Audio Technica MSR7, but returned them after a month. A bit shouty, with what seemed a serious lack of dynamic to me, despite a good tonal balance. Not very enjoyeable. I have now the Nad viso hp50 home, which is much better, but still lacks some weight (meat) in its sound. It remembers me the electrostatic sound. Bass extension is trully fantastic, but has no weight to it. Sounstage is maybe too big and diffuse for me. Not sure it will convice me. And then I remembered that Beyer had an old but excellent sounding DT150 (a younger relative of the DT48) which just might do the trick for me. I will try to share some impressions when they are home...
