On the E-MU page for 0404 USB it says:

"Premium 24-bit/192kHz A/D and D/A converters*
...
* Macintosh analog operation up to 96kHz and digital operation up to 48kHz only at this time."

Does this limit the SQ in practice when running on a Mac? Should not be a limitation unless playing SACD's right?

it limits the bitrate output, I fail to see how that would limit SQ, unless of course you're going to argue that 192khz is required for any listening, because oversampling or whatever whiney composition you may come up with

I don't know what a SACD would mean for SQ since I have never listened to one.

My impression is that SACD are sampled at 192khz so with my MacBook and E-MU 0404 usb I would not be able to try...

Funny enough it seems the 0202 usb does not have the same limitation:

"Premium 24-bit/192kHz A/D and D/A converters*
...
* Macintosh analog operation up to 96kHz only at this time."

If the 0202 usb uses the same D/A converters that might be a better solution for me then...

SACDs are in different format (DSD) so they can't be directly compared to PCM. Normally people say it's about 88.2 kHz / 24 bit. And how can you play SACD on Mac anyway? :O

I thought I could buy my own SACDs and rip the full bitstream but I guess they might be DRMed.

its nothing to do with DRM, its simply an incompatable format
SACD is its own format, like DVD, HD-DVD, bluray, etc, afaik no PC hardware can actually read it directly, you'd need an SACD player
