Okay so I wanted to get the Asus Xonar Essence STX when it came out because it boasts some of the best sound quality available in a sound card to date, yet I just recently purchased a HTIB setup that i was planning on upgrading to some new Polk speakers and such next summer when I free up some cash....the essence only allows surround sound output over SPDIF.....I do have some good quality headphones which is obviously what this sound card is marketed to, and I would be willing to purchase some amazing Headphones instead of new speakers for the home theater setup. Which do you guys prefer for GOOD listening when pertaining to music and stuff?? Some quality headphones? such as the Denon AH-D5000 or do you guys like to listen to your music through some full speakers?? If I didn't get the essence I would get the Xonar D2X instead and output analog to my receiver now....thanks for any help.
