I wasn't sure of that, thanks for clarifying.
All of these cards resample to 16-bit 48KHz if you use the DSP in any way because that is its native processing format.
Original Audigy forces resampling all the time, Audigy 2 and later will bypass the DSP as a fix to the issue, so unless you're running EAX or other DSP effects they will give you whatever they're set to give you. At least that's always been what I've read, been told, seen, etc.
You want X-Fi if you are concerned about the quality of SRC. The only time I've noticed the SRC issue on Live and Audigy is with synthetic tests that target its weaknesses (ie the Udial sample) and so I consider it one of those crazy OCD audiophile things. Also if you use Vista or later, Windows is typically set to resample to 16-bit 48KHz before sending data to the sound card, and so you bypass the Audigy's SRC (unless you use Alchemy or OpenAL).
X-Fi drivers are/were such a miserable nightmare though. 😒 I'd agree that, for the most part, the SRC thing isn't relevant to 99% of users, but I'm also doubting that it's much harder or more expensive to find an Audigy 2 or 2 ZS than an original, and they are improved boards.
The plain Audigy 4 does have EMU10K2 (aka CA10300).
Thanks for catching that one. 😀
