First of all I must say that this product is in my eyes only for the PC and not for the TV in the living room. For this, the power is too low and also the cable length. (Cable Length Rear 5m, cable length Front 2.5m)
Since I use this system on Pc hands it to me so completely out. All should have the Win 8.1 is the Win Download on the Asus support page 8 driver and not the Win 8.1 drivers. Since this is still in beta, I had a few problems with it. For my taste, came out at the beginning still not a good sound, it sounded bright and not so sick. I then made with the Asus Xonar tool in the Mixer setting a few changes and the increased sub bass. Now, although it is set well for me but I have a feeling that here but unfortunately missing a few watts. Therefore, a star less, with 10 watts more, it would be perfect.
Finally, I can as I said for all recommend this system to buy for your PC and do not want to spend more than 100.
