The ASUS Xonar DX (Rs 4,000 - 3 months ago, from KMD) is a rock solid card for music / movies and HTPC setups - has DDL so its perfect for most HTS-s with external decoders - and has Dolby Headphone, so its perfect for listening to music (and surround material) via headphones.
The only this that's wrong with it is the emulated EAX5.0 (GX 2.5) which doesn't work in most games. So if EAX 4,5 isn't important (and it shouldn't be), get the DX.
