What is the consensus for the power supply upgrade for a Squeezebox 3
for someone in 230V land? (Europe...)
The SB v3 has 5V 2A mentioned at the bottom side.
The Unifive switched supply (100-230V) delivers that.
This one can't?

Way past inaudible. Realistically, -100dB is inaudible. From that, then
-110 dB is no different than -140dB.
In a lot of cases, engineers consider -70dB "completely gone"

this is most interesting...
What I'm not seeing is the link between the small levels of DC noise
apparently present, and audible differences to the music.
And especially differences described in terms other than increased
audible noise (i.e. reduced SNR).

I always struggle somewhat with these descriptions,
AC noise is every bit as real and is found in practically all our

You do not hear noise per se in your music, the noise manifests itself
