You have to be careful with iTunes. for the best sound quality the EQ has to be off, the volume adjust should be at the center point (none), and the volume control at the upper left should always be at maximum. Otherwise the SQ will be affected. Any volume adjustments should only be with your preamp.
Also, a lot of low end DACs sound pretty good. Everybody hears things differently so there is never a consensus on anything in the Audio world.
