I'm afraid that would mostly just be doing the postal service a favor, by shipping it back across. I only got 4, and plan to use three on Sb- so will have to leave the offer open to Gary or someone else in the US I'm afraid.
They are reasonably priced though: http://www.at-view.co.uk/alwsr.htm > > I found something interesting over on AudioCircle.com about the origins > of 3.3Vdd for SB2... > > "Apparently, the 3.3Vdd for the DAC is not coming from a separate > regulator off the 14Vdc rails, but is coming off the switching > regulator (the 1st regulator shown in the above diagram) which is also > powering a slew of other stuff.

It does not affect the analog rails. But I'm not sure if Vdd is considered analog or digital. For what it's worth, you should take anything I say about so and so being connected w/ a grain of salt, if I haven't already demonstrated a lack of experience :) -- Skunk ------------------------------------------------------------------------ Skunk's Profile: http://forums.slimdevices.com/member.php?userid=2685 View this thread: http://forums.slimdevices.com/showthread.php?t=19822 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
