This last sentence got me thinking: the main difference between the
SB2 and SB3 is the use of a switching supply for the digital circuit in
the older model.

The much lauded Lawry DAC also has a generic switcher PS. It's a shame

And good to know, Meridian's SMPS are subpar. A shame given the prices

It's obvious the Unifive SMPS supplied with the SB, is quite
inexpensive. The elimination of the costly power transformer accounts
for the lower cost compared wit

The Lavry DA10 is very good, and highly recommended. I also had a Wadia

You are not comparing a power supply in a very expensive unit to the 99
cent adapter that comes with the SB, aren't you?
I understand that a switching mode power supply can be made reasonably
quiet, but it's not cheap. And be certain this is not the case with the

Thing is that the RFI generated from the switching power supply will
creep to other components, and this is not good.
RFI itself might introduce noise to the digital data stream, causing
extra jitter.

I've run several tests recording the digital output of my Preamp/DAC
every bit is getting through perfectly from the SB3. DTS perfectly. Who
cares about imperfect waveforms as long as they are being interpreted

I find AACPlus streams sound significantly better than MP3 ones. The
64kbps Radio Swiss Classic AACPlus stream is one of my favorites -- it
sounds better than MP3 streams at two or three times the bitrate. The
problem is that, for now, you cannot access them through

Absolutely!
I didn't mention the PS because it's pretty much mandatory to replace
it with a linear.

RFI is a very real problem with the 99 cent wall wart supplied. A
better power supply is mandatory, IMO, regardless of whether it has any
effect on jitter.

I would go for the BNC connectors and a 1:1 digital transformer at the
SPDIF output. This would measurably reduce jitter.

After seeing Sean Adams post that power supply (on his setup anyway)
made no difference in jitter. And the fact that all that matters is
jitter, since the SqueezeBox as far as I tested is bitperfect.
I don't want to bother doing mods that are based on just folks opinions

If you search the forums here, I think you'll find the SB digital volume
control issue has been well discussed. As I recall, there is no loss of
audio quality in using the SB volume control as long as you keep it in
the range above 40% or so.
What I did was set my SB3 volume at max and then play
