Quote:     Do you guys think it's worth upgrading from the Titanium HD to the ZxR /w AD827SQ's ?

  Can you explain this? Does the ZXR has warmer mids? Some time ago i'd compared the X-Fi Titanium (non-HD) against the Sound Blaster Z and found the Z to have a warmer sound (which i didn't like). The Titanium was colder (more neutral and easier to my ears). Also, how do you compare the highs...
