Pros: This is a hot little gadget, the blue vacuum tube glow is a sweet design. So as far as looks goes, its awesome. Luckily, it sounds pretty awesome too. Definitely an improvement over my dell vostro V130 laptop sound. The sound is good on its own, but once I installed the 5.1 software and pressed the NeoPC music button, it really came to life. Apparently it utilizes your CPU for sound processing, it works perfectly on my i3.
Cons: Word of caution! I initially had this plugged into a USB hub and all i heard was crackle, crackle, crackle! I thought it wasn't going to work, but then I had the genius idea to plug it directly into the laptop USB port and eureka, no problems after that.
Summary: vacuum tube design with blue glow is kinda cool.
Pros: None really..may be, the old vacuum tube looks and glow
Cons: This adapter is meant for experiencing DTS surround sound. I was hoping that it would some how make stereo sound clearer and distinct. But even after trying it out with a number of 5.1-channel test audio clips (from THX, DTS itself), I did not find it impressive at all. To me it does nothing but creates more noise, and cheap surround effect, but not DTS experience.
