The 1v2 switcher powers the CPU Core. In the SB2 (which I have) there
was a dual switcher in front of the 3v3 dig and 1v2 switcher. My
understanding is that with the SB3 they got rid of the dual switcher
and replaced it with a linear 3v3 and 1v2 switcher. I can address the
3v3 which powers everyth
Nice work Nuuk! Just came across this thread. Nuuk, I'm curious if one
of those reg boards is a replacement for the 1.2v switcher? Any
thoughts on whether this would be feasible and worthwhile?

Yes, I only use the digital output and one of my aims was to supply the
HCU04 direct. The aim is just to keep improving the PSU to see what
happens and I then plan to try the I2S mod with a DAC in the same
housing.
Those wires are routed through the RCA socket just to limit their
physical movemen

Prototype using separate regulators. Very encouraging so far but
'better' regs required. Sorry if this should be in DIY but it sort of
shows firedog what Phil Leigh is talking about, ie you can't just feed
in a 5v supply and expect to get the best from it.

I agree that the Duet and DAC route is much more flexible. The
Squeezebox technology seems to be moving faster than that in the rest
of the audio industry. A £100 box is something I don't mind swap
IMHO, what some people fail to appreciate is that with DAC's, it is a
matter of personal taste, even more than if one is 'better' than
another.
If you put all your money into a Transporter, you are stuck with the
internal DAC unless you want to spend even more money on an external
DAC, in which

That statement seems fool hearty and misguided. That is not the purpose
of the Duet. In my opinion, if one is going to do that, one bought the
wrong equipment in the first place.

Duet use should be with a linear PS and an external Dac. With those two
upgrades, your performance is equal to or better than a Transporter.
Try Acopian for a good linear PS for a lower price. I have one and
like it.

Well if you do decide to do this, don't go with the wellborne, he has a

Hi-
I've been told by a dealer (who also mods the units for personal use)
that a properly grounded linear power supply will noticeably improve
the sound of the Duet.
However the only suitable ones I can find are $300 (Channel Island
Audio) or $475 (Bolder Cables).
