Thanks for the suggestions, unfortunately they are too expensive, not available in Sweden or I will not be able to use my Feliks Elise tube headphone amp. Planars are too hard to drive with most tube amps.
And I just wanted some minor changes compared to my HD600. Oh, well...nothing in this ”hobby” will ever be simple. The same thing whith my Tannoy Eaton speakers. I just need some small changes to make them perfect for my me. Dream on. That speaker doesn't excist.
Thanks for the suggestions.
