Getting my Drop Senn HD6XX this week. Have an old AKG K701 that I like, but miss the deep bass and warmth. Couldn't resist this purchase. I have been researching 'phones for several weeks, but couldn't audition any because of my remote location.
I hope I made a good decision.
About me...athletic, retired engineer. I still dabble in electronics. I repair and align Tuners (remember them?). Not an "Audiophile", but I do like well balanced sound. Have old Levinson gear and B&W speakers. Oppo UDP-205 for digital. Schiit Jotunheim 'phone amp.Decent LP collection. Play lots of golf and hike. Prefer classical and opera from the romantic period...Wagner, Tschaikovsky, Mahler, Strauss, etc. Still listen to rock.
Can't wait for the 6XX to show.
