I like your post - but the Harman Target un
After I wrote that I checked a bunch of reviews and lists. Nothing I saw among the ones I have heard changes my mind (AT 50? ...please). Its true I wasn't into EQ when I heard Beyers, and the tuning on the ones I heard was indeed awful. DT 480? A remake of the fairly famous DT 48, both seem very scarce used. Name a more recent version that's obtainable and I might take it on.
AT 50? I did name a more recent version, the DT 150 which is currently made and easily obtainable, it's one of the few Beyers Tyll seemed to of liked. The DT 480 is a scarce headphone and it is related to the DT 48, the DT 48 driver was never really tuned ideally or it was tuned for very specific usage but it has a lot of potential.
