I`ve had the ATH-A900 LTD in 10 years and they still play very well indeed! I checked out the sound quality this week against the best they had in our local hi-fi store and the ones I heard wasn`t even close to my headphone. I tested it against Denon top model and B&W top model, and the other ones, not even close.   Superb bass, great treble, excellent sound!!
