Hi, I currently own the Asus Xonar D1 and was wondering if the upgrade is worth the money to the Auzentech X- Meridian 7.1 2G for 80 euros (102 US dollars)
I am currently using a Logitech Z906 speaker system and my two front speakers are from Infinity.
Possibly, but probably not. The problem is the D1/DX are very good cards for their price, and while cards like the HT Omega Claro Halo, Auzentech Meridian 2G, and ASUS Xonar D2(X) are a step up, for most people, the price probably doesn't justify the extra cost. Especially since you already own a D1...
That being said, ASUS and Auzentech tune their cards differently, so you might end up liking the sound signature on the 2G better; really couldn't say.
