Anticipation, there should also be a good sound card, then the device is probably superfluous! It is designed exclusively for STEREO, who looks for 5.1 or more is wrong here!
I for myself can say that both of my HP notebook (The sound output is gesoundet "Beats", very bad and disabled it is actually worse!), As well as to my AcerPC the unit has shined downright! I am rather come by chance into the pits and what can I say ... connected PC starts, dressed conditioning and only times just still amazed! So I really did not expect this! The sound is really much better, clearer, more powerful and much more details! Then I spent the rest of the afternoon in front of my conditioning and discovered my Spotify music collection :-)
