thanks for a very intersting info! I shall check those out more, meantime, I am thinking about these two i've digged out on the net: http://www.winic.com/2178sp.htm This one is really simple usb<->s/pdif converter - after emailing to manufacturer (Taiwan) and getting price list they are about $30 for single purchase plus shipping, etc. - sounds kinda good to me and considering that it is strictly very simply device - there should not be much issues with compatibility (manufacturer states that device is full duplex and USB audio standard compliant)... the other is from www.waveidea.com it is called UASC-1 (more expensive), but has all online purchashing fascilities, etc... don't know which way to go yet - but just thought people would find it interesting (esp. the first device - appears to be real cheap... - yeah i know it is gitial only - but that means that it modular (i.e. can use either high quality AD/DA converters or a cheapish DAT machines/ minidisc players, etc.)) > The problem with the M-audio usb stuff is that it > needs a very specific quality of AC voltage to operate, > which makes destroys the key advantage of having an audio > interface on a laptop.
