Cambridge 840C as a DAC

You need a new sound card, either internal or external with a digital output.

I use my 840C's DACs with a Squeezebox Classic and this is a huge improvement over the internal SB DAC. And because I use a wireless router at home I can listen to lossless uploaded CDs via iTunes through the SB into the 840C. This is an exceptional solution and works very well.

Face, When you say a 'Sound Card' is that something I can connect to my computer through a usb output that then has the appropriate digital connections for the 840?

Yes, check out http://www.newegg.com, they have a decent selection of USB sound cards. I've have good results with Creative and ASUS products.

WOW, am I glad I spotted this thread.

I am experimenting with Airport Express, to optical / CA840c and by balanced to my stereo. All files are Apple Lossless some recorded w/error correction ON. The 840c says the bitstream is 18bit, 44.1khz.....is That correct?

Problem is that every once in a while the stereo emits a very Glassy, edgy, fingers on chalkboard sound. It doesn't repeat if I 'rewind' and play that section of the song a 2nd time.

Any suggestions would be greatly appreciated. Apple is clueless, so far, and I have yet to hear back from Cambridge.
