I have a DT48S from 1967, date can be seen if you open them.
When I was young, say 23 or so, I had a DT48A, the medical lab version (guess 25 Ohm) with the
round grey pads. Terrible pads as I remember.
Gave it away or exchanged it with someone, I don't remember.
But... I never forgot the sound.
Now I'm 44, a year ago I bought a DT48S with a Tandberg 3000x reel2reel.
Weird.. when I was 23 I also had a Tandberg 3000x r2r, and with the DT48A.
65 euro for the both together. A bargain.
I use my DT48S every day. I leave my AKG K 272 HD on the wall.
Yes bass is far more available on the AKG, so I left the DT48S on the wall.
I switched a lot. But now for a year it's only the DT48S.
It's so precise, so detailed, and for most ... fast...
Next month a tecnician will have a look at it whether it needs some
internal cleaning. I think my right can would benefit from it.
For me the DT48S is the most pleasant headphone.
If I realy want to enjoy my music it will be with my speakers (Elipson 1303FT).
On my Sony TA-E86 and TA-N86 from 1979.
