A S/PDIF Coaxial to Optical Converter

    Well, I posted this question once and got no reply, but I was probably in the wrong section, so here goes again:

    I am getting a PowerMac G5 (which has an s/pdif optical in) and i have an Apogee Mini-me (which has coaxial s/pdif, xlr AES/EBU, and usb outputs). I do not want to be limited to 24-bit 48khz from the Mini-me's usb output (which I've been using up to now), so I was thinking of somehow using the coaxial ouput and converting it to optical. I'm also wondering if, in general, there are benefits to s/pdif and AES/EBU over usb?

    In regards to the s/pdif conversion, I have just looked on google and found M Audio has a product called a CO2, which does precisely want I want. Does anyone have experience with this product or something similar? Is there a possibility of degrading the signal in any way from converting coaxial to optical?

    Thanks for your time, and I appreciate any responses.

    Although there shoudn't be, there certainly could be. Without good ears, great monitors, and no other weak links, I would not think that you would be able to tell one from the other.

    Thanks for your reply, AudioGaff.

    Is the M Audio CO2 a quality component, or are there other converters that would deliver superior results? I would rather get the right piece of equipment for my system than just buy the first one I find.

    Your limited in what choics you have available. Other than the one made by Hosa, I can't tthink of another that is only two channel. All the others I'm aware of come in multichanel versions. RME makes a conversion unit that is high quality and yet affordable for what you get.

    I use and have used an older Alesis AI1, or one my effects units such as TC M5000 or Lexicon 300L which amy or may not be better in quality than the M-audio unit, but are least units that I trust.

    As to S/PDIF vs AES, there was more of a difference many years ago. When it comes to the basic raw digital audio data, they both are the same.

    In theory yes. Most of the time though, digital is digital. It does not sort go a "little bad", it becomes "very ugly". I would bet quite a bit of money on that you will have absolutely no problems and absolutely no degradation in sound. Of course you will need to look in setting the synch sources right and that kind of stuff, otherwise you will probably get no sound or a lot of clicks (no subtle degradtion here).
