But the durability is a terrible problem!

The biggest problem may be listening to them to loud and hurt your ears.

The only real problem with the HD 600's is that if there are any imperfections in your music, such as problems with sound mastering or just being an MP3 you converted from YouTube, you will hear every imperfection

If you're going with a stationary home DAC, then make sure that it has balanced outputs, and get a true balanced amplifier (Headamp GS-X is a good model, as is the Heardoom Max Balanced, or perhaps a cheaper but still excellent SFT-build balanced M^3)
