Sony CDXGT805 / CDX-GT805DX / CDX-GT805DX CD player with MP3/WMA playback
Unbelievable!    The sound quality coming out of this beast is incredible.  The ITA and the HDEQ does wonders for the sound stage.  WOW!     I can independently adjust each speaker position so that the sound waves arrive all at the same time from each speaker to my ear.  Also, you can adjust the equalizer for each speaker for many frequencies +/- 6 dB.  DSO 3d is another cool feature that I enjoy fiddling with (you can adjust height, width, and depth).  I cannot say enough about this head unit.
