I can measure the noise. Maybe you can't, but it is there. -Especially on the clock chip.- I can show the difference in noise sidebands on the SPDIF output. If I am not mistaken, I may have posted that on this, or other, forums. Whether or not the linear supply has less noise.............just because it is linear is no guarantee it is "low noise". Most are not. Additionally, the noise from the local regulators -can- override the noise of the external linear.
