I don't doubt your experiences. And I am not saying that in all cases an upgraded PSU will improve the sound. But this comment by Tyler: "An external supply can't eliminate the noise from the internal switcher." suggested that using an external linear supply would provide absolutely no benefit since the internal supply was a switcher. It's like saying upgraded power cords are a waste because they do nothing to change the wiring inside your walls. Yet, my experience is that upgraded power cords can make a difference, though not always for the better. I always thought it was a given that eliminating as much RF noise as you can was a good thing. Apaprently, some people disagree. Now, maybe their systems simply aren't that sensitive to RF noise or they can't hear the effects of it on their systems for whatever reasons. I don't know. Maybe other sources of RF noise exists in their homes that mask any benefits that could be had by using a linear supply. Or maybe this whole RF noise paranoia is juts that. It's entirely possible, in systems other than your own, that an upgraded linear PSU could have an effect on the sound, even through the digital output. I don't really care either way. I have no vested interest. I don't even use my Squeezebox now that I have a CEC belt drive transport. I still might try the upgraded PSU to see if it lifts the Squeezebox to the level of my CEC but I highly doubt it will. -- SatoriGFX ------------------------------------------------------------------------ SatoriGFX's Profile: http://forums.slimdevices.com/member.php?userid=8852 View this thread: http://forums.slimdevices.com/showthread.php?t=38738 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
