Shrill low-bitrate, lower-fidelity digital sound just doesn't evoke that feeling in us. The same way no one is asking for RealMedia videos on their home theater system, but prefer film grain on video and 3D CGI to look "messy" (another analog noise characteristic). We humans love noise apparently! I guess evolution built us for a noisy and messy world and digital sound just seems off to us. We'll make an effort to get closer to analog warmth but do out best to flee digital shrill.
