Logitech bought Slim Devices, who used to make the squeezebox.... and the logitech transporter costs 2K now. 
Allthough the old squeezebox is now only $300
Logitech Transporter USD 1999.99
Logitech Sqeezebox USD 299.99

An externally hosted image should be here but it was not working when we last tested it.

Ah thanks weissi, according to datasheet, this dac only receives left justified input. CS4344 would accept I2S input - so out of luck there.
That's a good price for the squeezebox now but I will probably go down the route on peufeu's thread - high quality multichannel audio over ethernet http://www.diyaudio.com/forums/showthread.php?s=&threadid=85473&perpage=10&pagenumber=1
I just found appealing the idea of an exsiting box with decent form factor and all the user interfaces sorted out for two channel audio as an interim solution especially if it had another set of functionality ie. cable TV decoding
So my question is what does U750 do next to the audio outputs? Also what about the pin header on the upper right hand corner of the circuit board right behind the LED? It's interesting it seems to be able to take more RAM with that expansion port, least I think it's for RAM.

U750 may be for some sort of digital output, being that is is very close to the DAC input. I'll be having a very close look at this board once mine arrives.
Look closer at the "expansion port", the wifi card is plugged into it.

Thanks weissi.
Here's an out-of-focus close up pic of U750. Doesn't look like an IC layout, more like a connector. Is it for a SPDIF output connector?

Well most everything would appear to almost exactly like the evaluation board so extra output would most likely be a Toslink like weissi said. Hmm, think I might need to order one of these to play around with it.

That's what I thought, but the pin layout is different - 4 pins vs. 3 pins . This appears to be same layout for all Toslinks.

Well something like a GP1FA511TZ from digikey has only 3 pins. I'm guessing it's something along those lines and it would be little easier to have the exact pin spacing.

Not too much to report. I think I found the correct SPDIF connector that should fit U750. I know, I2S is desired, but, I haven't heard back from BridgeCo on their chip and it doesn't appear that you can tap I2S off of the current DAC.
Anyway, if anyone is interested Digikey has the TOTX141PFT ($2.70) and TOTX179PFT ($4.12) which should fit, I think. Right now they are out of TOTX141, but have 1500+ of the TOTX179. I'm about to order one, but want to get other parts for the order.
Thanks for the update. I also purchased one of these and have been following the thread here and on av123forum.
Have you had a chance to verify that the spdif signal is indeed supplied to those pads on the pc board? I was thinking of checking it out with a scope this weekend.
The DM830 datasheet seems to be unavailable online. Has anyone had any luck?
I too would like to tap off I2S, but if the DAC is 4345 it supports only MSB Justified, so the DM830 must be programmed that way. A pity.
However, it may be possible to convert MSB Justified to I2S with a simple circuit. The timing looks almost identical ( at a glance, that is ) except for WCLK polarity and I2S seems to delay by a clock cycle after the WCLK transition.

I just bought a white squeezeBox for $229 with free shipping from SlimDevices with their sale in May. Use the promo code "LIVE365" for a $20 discount. BTW.. The sale price was $249, but the discount code for the $20 still works.
