SLI soundcards?

As I've been saying in this thread, get a USB DAC and a headphone amp, they're generally better engineered than internal sound cards. I personally use a Schiit Modi DAC and an Objective 2 amp, but there are cheaper options out there. An O2 is overkill if all you need to drive is an MDR V6.

This might be a good bare minimum amp/DAC combo for you. Should have enough power to drive MDR-V6s okay. I asked someone who owns one, he says it's OK but the volume knob is a little fiddly. You could get around that by using software volume control though.

It's just a card with more ports, it doesn't plug into the motherboard. Like the old live drive breakout boxes, but in the back.

What dac do you have?
Any dac suggestion everybody?

What's your budget, and what are you going to use it for? Are you sure you even need one? Do you have any of the problems described in (hissing, clicking, buzzing, too quiet, no line out?) If not, you probably don't need a DAC.
