In my office the sound from the computer goes from 3.5mm socket to the amp input. Works OK but there is a low level buzz.
So, how to upgrade a bit ?
My computer is a "slim" case , so normal soundcards don't fit.
I have a couple of spare DACs, but no SPDIF output on the computer.
Would the easiest / cheapest compromise be a cheap USB DAC from Ebay ?

Does computer have an earthed case?
I can get this a bit with the notebooks, it's caused by the SMPS mains adaptor and no mains earth wire. The solution is have earth lift resistors on whatever it's plugged into.

The USB connector on the above item looks remarkably similar to the one on my printer.
Is it likely to be the same ?
Link again.

EDIT.
Looks like USB 2 type B.

I was not aware that USB 1 or 2 affects the design of the connector.
Unless anyone else knows differently...

I got the "widget" USB - SPDIF converter in the post today.
I've plumbed it in and using my old AK4393 DAC, my computer sound quality has gone up quite a bit.
Well pleased.

If I make my "spare" PC into a Vortexbox clone, would a CD optical drive be preferable to a DVD optical drive ?
My thinking was the CD drive being a slower speed might make it easier for the ripping.

If you just want to rip audio CD's then DVD drive is plenty good enough. If not over qualified!
