If you were to remove the cover on the sound core 3d, you would find a very simmilar chip. The sound core 3d does have a higher SNR value, but the X-fi titanium has 32 bit audio, something that the Sound Core 3d can't match.
The X-fi can also process audio, without help from the CPU, also something the Sound Core 3d can't match.
This is per Creatives website:
"•Max. Playback Quality
24-bit / 192kHz (Stereo-Direct Mode)
24-bit / 96kHz (5.1)
•Audio Fidelity
Up to 24-bit / 192kHz"
Not sure where you are getting your information but the X-Fi Titanium HD has the same audio specs (almost) as the Z series. 24bit is the normal max audio quality.
Also the X-Fi Titanium HD does not have a good of a headphone amp (330Ohms vs 600Ohms) which means it wont be able to drive higher end headphones as well as the Z series.
Pinhedd,
I had heard of that. I never got that just that I had to go in and change modes to get audio to work with every boot up of the system.
Honestly, you should move to a Z. Its just as good, if not better, and has some nice features.
