Hi everyone, new here and very interested in getting some HD 600's, great thread!
As a speaker designer I'm interested in a couple of the points over the last few pages and I have my own opinions on them:
Burn-in - it's real but realistically takes maybe a dozen hours use at a reasonable volume before any changes in compliancy are all done, after that point no measurable changes occur. The "100's of hours thing is most likely just personal adjustment to the sound.
That's my view on it anyway for what it's worth!
Jimrod76 - you did not go enough pages back to really see what the reintroduction of burning-in was talking about. I was talking about my hybrid tube amp the Little Dot Mk IV / SE (se version comes with better tubes) and I am absolutely sure I have witnessed a tremendous improvement after it burned in listening with my Sennheiser HD 600s.
The people on the The Little Dot Mk IV / SE appreciation thread are not impressed with the tubes that come with se. But I am wondering if they gave burning a chance or don't have a se. I would really appreciate comments on if other people on this thread are observing tremendous improvement in tube amp sound after burning-in with their respective tube amps.
