I have had the same experience with an Apple TV as the music revser. The basic line outs on these type devices just are not high fidelity. The Tube Magic D1 DAC is so much better with either the solid state or tube output that with lossless or WAV files you can actually do some critical listening. It is very close to a good CD player. I used the D1 with my computer at work for a couple of days to accelerate break-in and was really surprised that the USB DAC+headphone output sounded better than my NuForce Ikon mobile.
