S/Pdiff and USB?

In my study we have at least one laptop and an Apple iMac all the time. And it would come in handy if I could output quality audio to my stereo not just by using the Apple Airport Express but also from other sources than iTunes.

I found his DAC on eBay, and it was very cheap although it uses quality components for the DAC and its receiver. What also comes in handy: It does not require a channel received but apparently trusts me to use one input at a time.

The kit

Dimensions: 110 x 80 mm
DAC: CS4398
Receiver: CS8416
Opamp: 5532

Seller: eBay

Building

As said before, building the kit is not that easy at all. Fortunately I received some more material/documents from the eBay seller:

Schematics of the board
Layout document of the PCB
Datasheet CS4398 The datasheet for the CS4398 DAC chip
Datasheet CS8416 The official Datasheet for the Cirrus CS8416 receiver

Finished

The pictures of the finished DAC are following below... For the moment I have just mounted the whole thing on a piece of wood I had laying around. I now it is not pretty, but at the moment I have more DACs around than input on my amplifiers so it makes no sense to have all of them in a nice case.

As you can see I just changed some of the kit capacitors for some "better" ones I had in stock.

Power

The power requirements are simple for this DAC, only a single supply of 15-0-15Vac is needed.
