There are conflicting reports between different sources, but does the ad-usb1 convert the sounds digitally or does it just convert it in analog?

It doesn't "convert" anything -- it just outputs a digital signal. You can use it with any device that has an optical digital input. It doesn't have an analog output. The M-Audio Sonica is a similar device (about equally priced) that you might consider if you need both digital and analog outputs.

what? doesnt it at least convert that digital signal into optical?

Since the signal is digital already, you don't usually say it "converts" to optical which is also digital.

hm, in that case, won't all these usb audio devices sound the same if nothing is converted?

 

[Wodgy]

Yes, in theory they should all sound the same. In practice, that's not always the case. Some devices, notably some of the Edirol products, upsample all audio to 48 kHz before outputting the digital signal. You want to avoid this at all costs. I know the Sonica doesn't do this, and the Sharp is fairly new so it probably also doesn't (but I can't say for sure). Also, different devices can have different amounts of jitter. The effect of jitter on the sound is debated, and depends heavily on associated components, but I think I can detect a difference in the quality of the digital outs between my Delta DI/O 24/96 and my Sonica, but the difference is minor. As long as you get a decent device I wouldn't worry about it.

"Don’t have a surround sound receiver or 5.1 speakers? No problem. Sonica’s built-in TruSurround XT™ technology gives you simulated surround sound over your existing powered stereo speakers. Using patented TruBass™ technology, Sonica can even increase the perceived bass output of your existing speakers.'

Is that defeatable?

 

[Wodgy]

Yes, it's defeatable. (I always keep it turned off, since it does nothing positive for the sound.)
