So after being really into my 225i's for a while, I got kind of tired of them and went back to my HD555s for a few months. I was convinced that I preferred the 555s, and I was about to sell both of them and move up to a lone pair of hd600s -- I decided to give the 225s another go around, and I've been sitting here listening to LCD Soundsystem this morning. I forgot how great these can sound. Why oh why can't they be a bit more comfortable on the ear? I think I might go ahead and live with it, as these are as hi-fi a sound as I've heard in my limited experience.
Also, definitely amp these things up if you can guys. They sound great unamped, but they sound worlds better after being amped. Cannot stress that enough. I run them out of an integrated, and they sound great.
