Squeezebox Vs Duet

SB3 – 5VDC 1amp- Acopian -B5G120

DUET- 9VDC .5 amp- Acopian -B9G50

These power supplies have screw terminals.

You'll need an AC power cable and a DC cable and plug. Make sure you check the stock wall wart for the correct polarity on the DC plug.

I have never listened to either of these units. However, I can tell you 2 things:

1.) The digital outputs are the identical design.

2.) The Duet has lass crap on the supply rails, as the outboard SMPS does not have to power the display. There is still too much noise on the clock's supply on the Duet, but with a decent linear supply, there is hope for it.

Kana or Art,

Channel Islands Audio shows this for their linear PS
Output Voltage: 9V DC @ 2.5 Amps

The Acopian is 9V 0.5 Amps

The switching PS with the Duet shows 9V and 0.56 Amps

Is the Channel Islands Amp specced wrong or should a different model Acopian be used as the amps are different? (I don't know much about this!)

Thanks.

The Duet doesn't need 2.5amps.

If it did, SD would have included a 2.5 amp wall wart.
