Weeding through this thread, am I correct in saying that people do not
feel that the upgraded PSUs (CI Audio or the Bolder-modded Elpac PSU)
will make a big difference if I am using SB3's digital stream?
Also, can someone explain the internal switching mentioned earlier?

Yes you are correct. Most posts I have read state that the poster could
hear no improvement... I still have to try it out for myself. I do not
expect to hear an improvement after using a linear psu. My spdif out is
feeding a RAKK DAC MKII. But I have read a few that say it did make a
difference

But it can reduce jitter, or at least it could on the SB2:

Whether the change in jitter is audible is up for debate. I too quit
using the linear supply when I went with an external DAC
Has anyone ordered one yet?
If so, let it know how it looks, sounds, etc.
Thanks

The US supplies don't have a core at the end. They don't need one to
pass regulatory compliance where the UK supply does. Simple as
I don't know if the US supplies are different but the UK ones ship with
a ferrite core at the SB end of the cable. This probably does keep some
of the RFI out of the SB.

Not at all. I think they are selling them for $259 and that includes
shipping. Sounds reasonable to me.

In the past I fashioned my own 5VDC 5A supply for about $100 in parts. I
found that it made an obvious difference when using the SB3's analog

the SB3's digital output to drive it - that resulted in a larger

Nobody claimed it could. But, to say that then means that using an

I can't comment on the analogue stages of the SB3 (as I don't use them)
but a replacement PSU makes NO difference to the digital output as far
as I am concerned. I do use a linear PSU because the stock supply

If the issue is RFI being generated by the supplied wall-wart, making it
across the SB3 onto the analog output cables, then a cheaper solution
would be to put an RF choke, (wrap the DC cable into a bunch of turns
around a ferrite bead,) right before the cable goes into the SB3.
