I having been using the Strix Raid DLX for the last 2 days, doing and A/B comparison with my Razer Barracuda AC-1. Personally, there isn't much difference. I think the DLX has the edge, but its so small it isn't worth spending $219 on the DLX over Barracuda. In BF4 they sound almost identical. With music, its really close. The control box is cool on the DLX, but I don't even really use it.
I'll probably stick with my barracuda. I also have a Recon3d, which is not as good as the other two offerings. I think getting a Soar would be fine, or a Sound blaster Z. The positional audio is really good on the DLX. I'm not a dolby fan and the virtual surround sound on the DLX sound very similar to the THX studio on the Recon3d which I like.
I've had no real issues with the software. There was a time the control box wouldn't switch between headphones and speakers. When not in use, the control box does a Knight Rider type strobe with the lights which is really cool. I'm watching it right now. I doubt I'll keep it. I'd rather keep the Barracuda/ Recon3d and maybe add a Schitt Vali 2/Modi uber 2. That way I get a great amp and dac, plus I can use the surround sound settings of those cards as well.
