I recently stumbled upon a nice flash-enabled Sony Walkman website that provides some really interesting info on current technology used Sony Walkman. Usually Sony Japan has a really cool and informative info located on their Sony Walkman portal (currently promoted as PlayYou) but for English speaking population the content also matters.
Anyways, on that Walkman Portal check out the Why Walkman section as well as Walkman Heritage. Walkman X series is not listed on there however we all know it features Clear Audio Technology (Clear Bass, Clear Stereo, DSEE), so teleport yourself to learn the inside info on what makes Sony Walkman sound so good.
