If you want to keep using Dolby Headphone, then the Xonar U3 might be an option. It's pretty much the USB version of the DG(X). I'm not sure if it's cheaper for you to get there though.

Thanks. I thought it might have distorted the sound or something. Glad to have this cleared up.

On the X-Fi Titanium HD, does CMSS-3D Headphone work fine if you use the RCA out?

Yeah it doesn't fit. Time to do a bit of modding.

Ended up ordering it, will let you know how it goes.

Think these will work?   http://www.ebay.ca/itm/190702655747?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

  My guess is you should be OK.

  Depends. How close will the SBZ sit to your video card(s)? And are they loud? I had a hissing/interference issue with the Sound Blaster Zx whenever my video cards started to work hard.

    Does anyone know if using an amp out of a X-Fi Titanium (hd or non) would solve the hissing/interference sounds? Or would it just make it louder?     I've tried a few external USB sound cards, and none of them really sit well with me. I've used:   X-Fi Surround 5.1 SB1090: it has...

Was taking a look at the Blue Snowflake, seems decent enough. Attach to top of monitor, and it's cardioid so it shouldn't pick up too much background noise.   http://bluemic.com/snowflake/

  I see. Thanks for the info.

Does the U7 have GX 2.5/3? Or none at all?   In the past I have used a Xonar DGX, with the GX button enabled. In game for Counter-Strike Global Offensive, I have snd_legacy_surround 1 Audio options 5.1 instead of headphones   That setup sounds great for positional audio I find with my PC...

  Yeah I've been looking at those. At the moment I have been gaming in entertainment mode on the Titanium. It's not too bad.

  Thanks! Appreciate it.

It seems like the Recon3D USB's only do THX, or am I missing something?
