I've been contemplating selling my AKG K1000 for over a week. Now the USD is stronger to the pound, and selling it at a mere 1000 USD would get me back all the money I've spent on getting the AKG K1000. Which would be quite reasonable.
However, I've decided tonight that I will not sell off the K1000. Why? Because it's the ultimate reference headphone for classical music. It should be noted that it only performs on classical music, and maybe operas but nothing else.
It doesn't do well in jazz, it's too bright, revealing and aggressive. It doesn't do well with indie vocals (read: Feist, Goldfrapp) because of their extended mids/highs and the dreamy soundscapes. The intimacy and the caved in feel is required for these kinds of music. It doesn't do well in rock, despite it's amazing speed and clarity to detail. You would expect it to, because it does so amazingly well to play out the nuances in Hotel California (Eagles: XRCD). However, it seems so much more right to listen to Bohemian Rhapsody (Queen: MFSL Gold reissue) or Temptation (Diana Krall) on the HD600 (only single ended for now).
When I try something like Vivaldi's Four Seasons, Dvorak's 9th, or Beethoven's Triple Concerto, it just doesn't work as well with the HD600. There's so much missing that I just don't enjoy it like I do. Surely, only classical music is the K1000's forte and nothing else.
Clearly, it is a pair of serious headphones, intended for serious listening sessions. I am thinking that there is a headphone out there that offers the best of both worlds. Until then, I shall keep to both.
