On the box it says VDC-SB.
It's been discontinued. Their new power supply's work with a squeezebox and other media streamers.
BUT!! I have my SB3 connected to a very good DAC by a coaxial cable. So I'm not sure if a power supply would help.
I'm happy with what I hear now.
I'm thinking that if I get a CIA power supply I'd bypass the DAC and run audio cables to my preamp and
that way maybe I'd be able to compare sound with and without the CIA power supply.
AAAAHHHHHH!!!! Audio!!! Isn't it GREAT!!! All of us are looking for tweaks. RIGHT???
