Hi,
I took a quick look into the inside of my Sonos Port today. I know the warranty is void now, but just couldn't help it, curiosity won.
To open the case, I did start at the bottom by removing the big glued rubber pad. Right in the middle was another foil cap covering one screw with a TX10 head.
After using a plastic lever to open the clipped sides of the case...
Removing the screws holding the cast piece of metal in place, did emerge the analog board I was very happy to see some well established components like the AK4490EQ on there.
Where I painted the question mark, I assume one of the ICs is a s/pdif transceiver for the coax out.
Removing the last screwed part did reveal what's under the shield.
ARM Cortex A9 as the Main CPU I assume, RAM and clock buffer (not shown in the pictures), as well as an Ethernet switch IC for the two ports on the back.
There is another smaller CPU on the other side. Do you guys have any idea for what purpose?
One of my intentions was to see if I can find the master clock for dac/adc/coax. But all the crystal oscillators where beneath CPU and network. Left me a bit unsatisfied
All things considered, the build quality and used components are really great. But for €450 one would expect that.
If one of you guys in Europe would be willing to measure the port, I could mail it to you. After seeing the components, it would be interesting to know how good it was implemented.
Cheers
