I have the oem Recon 3d version , going to a set of Bheringer ms20 active monitors , and it is awsome . Nice clear and crisp , and the bass is unreal ,to the point of having it near enough set to flat . And just controlling it through the speakers . When using a headset through the jack on the speakers whilst running on onboard it sounded awful , but now if anything it is better than the speakers alone .
For the price £43 it is a bargain I will never go back to onboard sound again . There is only 1 issue I have found is if you adjust any setting on the go , you sometimes loose the sound , and have to go back into audio manager , and reasign the output . I'm sure it will get fixed in a driver update .
