Well I got it yesterday. The SonicXplosion. Sounds great. Gaming is different, I'll have to get used to actual 3d positional sounds.
The headphone amp onboard is brilliant. I can take it very loud without distortions. Where as on my onboard if it was loud it sounded shit. I had to swap a jumper then plug into the blue jack. If I plug my earbuds into the normal output its very weak.
Fully gold plated + 5 year warranty, I think I'll be keeping this for a few years at least.
Any problems or even small flaws? Where u using your onboard sound before that? If so what motherboard do you have? Is the sound difference defintely noticeable?
