I own the HD25, HD25 amperior, HD25 Aluminium, Beyer DT1350 and HD26 PRO.
HD26 wins in my book. Terrific mids. Better treble with well extended bass superb isolation & comfort.

agreed based on my limited time with them at RMAF, they are clearly superior.
yup at 2013 Rocky Mountain Audio Fest. Spent most of my time at the Sennheiser booth with those on my head. Best on ears I have heard in a long time. And I used to own Amperiors and DT-1350s.
Thank you mate. But due to budget issue, I can't get other headphone yet. Unless I sell my Amperior, which I think I don't willing too. :(
