I must say I'm really curious about alternative HRTF technologies to CMSS Headphones, namely Dolby Headphones found on Asus cards and SBX found on latest SoundBlaster Z cards. Some people say CMSS is the most precise, but also too analytical and dull, while Dolby is more immersive, but adding plenty of reverb which might be not for everyone, and SBX is a balance between precision of CMSS on immersion of Dolby.
I've checked several DAC/Amp's under $300, and from their specs, they are equal or inferior to Xonar Essence or ZxR cards.
If I understand, WM8741 Wolfsons would be inferior to PCM1792A (Xonar) and PCM1794A (ZxR)?
So, do you still think a $250-$300 DAC/Amp would give me a better sound, then Xonar Essence or ZxR?
I'm afraid I can't answer your questions Re- CMSS vz SBX vs Dolby and I'd suggest asking in this thread- http://www.head-fi.org/t/593050/the-nameless-guide-to-pc-gaming-audio-with-binaural-headphone-surround-sound/2610#post_10260354
There are a few members who regularly post there who are likely to know and also a few others who have the Audio-GD 15:32 and should be able to offer a rough comparison with the various high end cards. Some have compared it favourably with the STX so it must be up there.
The specs of the DAC's used isn't always a foolproof way of determining which kit should perform the best, the implementation is usually much more important.
1. Computer cases are very hostile environments for audio devices to reside in and can pick up noise in some instances.
2. By connecting to an external DAC using optical you are galvanicaly isolating the DAC from the PC.
3. An external DAC usually has it's own dedicated power supply which can also easily be upgraded if not as clean as you'd like.
4. External DAC's are usually more versatile and can be used to connect lots of different kit
5. Again, I don't know of any soundcards with a z out of less than <10 Ohms which is not ideal in your case. External DAC's often have a low impedance output which makes them better suited to low impedance headphones like your AD900X's
On a side note, I recently bought a SB Z and can't say I was very impressed. It didn't work very well at all with my TF10's (32 Ohms) due to the shifting FR and Harmonics (1:8 output impedance rule) but as I predicted they sounded a lot better when I added to the chain and connected to my (low z out) Pioneer amp first.
The SB Z sounded quite harsh and grainy compared to my old Audigy 2 ZS, maybe if I had given it more time I might have aclimatised to the sound but because it wasn't a clear improvement over the old card it went back to the shop... I'm back to using the old ZS again but plan to get myself a new external DAC/headphone amp when funds allow.

It's at least as good sounding as my Essence STX (AD797BR), and there is zero background noise.
The 15.32's 2-Ohm impedance might have slightly improved the audio quality of my 32-Ohm AKG K550s
Anyone notice if the 15.32 improves with break in?
