This is a good system, though I tend to use my own MP3 player and a couple of albums that I know really well from my hi-fi (which has small but high-quality studio monitors). The key point is to listen for details and the separation between instruments. If you just listen to the music, the human ear&#x2F;brain is far too good at filling in the missing bits...<p>I&#x27;m not sure any headphones can give you a proper 3D sound stage of the sort that you can get with good loudspeakers (especially the LS3&#x2F;5a). For that, I use recordings of Shostakovitch&#x27;s string quartets to see how well I can locate (and distinguish between) four instruments.<p>Although I&#x27;m not fond of it as music, Ravel&#x27;s Bolero is also a good test track for headphones, because of the way the same theme is repeated by many different instruments.<p>I use Audio-Technica ATH-ANC7b noise-cancelling headphones, but I don&#x27;t think there&#x27;s one headset that suits everyone, any more than there&#x27;s one pair of speakers, or one car....
