I can imagine that 25s are very effective for Rammstein! The TMA-1's would seem to be one of the obvious rivals to the 25s in the same price range and there are reviews around comparing them.
What I'd like to hear is what cheaper alternatives might be to 25s for people who want something similar, either in sonic qualities (lots of prAT! and detail resolving power) or toughness and isolation in a portable size.
For the first, I was wondering if anyone can compare the 25s to PX200s - although 200s do seem to have a rep for falling apart? And for the second, maybe those Cortex CHP-2500 phones that people are raving about? Or are they over the ear phones and too big to be as portable?
