Default Laptop to DAC interface

Hi,

I own a dac which will accept either optical or coaxial inputs and after a search on this forum and google I am more confused than ever.

I wish to send audio from my aging Toshiba laptop with windows XP, to my
external dac ( as mentioned optical or coax inputs only ) The laptop provides usb out and I thought that all I needed was a usb to digital coaxial cable. It appears though that this ' cable ' does not exist.

So can I diy something that will work ?

Search for USB to SPDIF, you'll find plenty. USB to optical might be better because of electrical isolation (ground loops and such...).

M2Tech Highface is a very nice USB transport as well. I own it for more than six months and I'm very happy with it.

OK, so I need some sort of interface. The M2tech is pricey but I found this at about one third the price.

Monitor 01 USD-??? MUSILAND -

Is this what I need and does anybody have any opinion on its sound

Yes, it is a great product and does the job pretty well. Drivers work flawless but only under MSWin. Does not work for Linux.

It uses a-synchronous data transfer which is the only proper way to have low jitter.

Hi,

I have stumbled across a demo model Bel Canto USB Link at a good price locally. This would be cheaper than importing the Musiland, but which one sounds better.

Perhaps someone has compared them and could comment

Don't spend too much. Here's one that has also received favorable reviews, and it's a one-chip solution:

Duh??? $129 is way, way too much for a simple PCM2704 (costing barely $3) implementation the Hagerman provides. For much less many others are around.

You can get several pcm 270x/290x based variations on ebay for like 30-something bucks, shipping included. Or if you settle with optical output another one at a fair price could be Behringer UCA-202 (pcm 2906 based plus some opamp, IIRC).

As Pjotr said, don't waste more money on it.
