Hello,
I'm going to buy a sound card ASUS Xonar Phoebus. On the market there are three models differ, of course, but also the product code and price. They are marked:
1. 90-YAA0M0-0UAN0Bz
2. 90-YAA0M1-0UAN0Bz
3. 90-YAA0M2-0UAN0Bz
Can someone explain to me what are the major differences between these products and that is most profitable to buy?
