So Macs have good internal DACs, can someone comment on how much better this unit makes music sound while running off a Mac (I have a 2013 Mac Air)?

I disagree with KM. Haven't tried this AudioEngine DAC, but the NUforce Mac-specific DAC I own makes a noticeable difference, mostly in the clarity of the highs. It makes the Mac's built-in DAC sound shrill. On lower-end headphones it might not be detectable. And, of course, everyone's hearing is different. I can listen to Google Play streaming much longer on my Sennheiser HD280 Pro headphones through an external DAC than without one.

Will the analog outputs be bypassed if a headphone is connected at the same time?

Yes Zack. The analog RCA's are disconnected if headphones are plugged into the D1. I wish it was a bit more flexible but that's the way it is with this unit.

Does this DAC require LPCM or PCM in S/PDIF input signal. Most TV has option to output in PCM format but not all. My LG DU-37LZ30 has DTS/AC-3 output

From the FAQ on Audioengine's site:Q: The D1 is connected to the optical output of my TV but I'm not getting any sound. What can I do?A: In your TV menu verify that "PCM STEREO" is selected and "DOLBY DIGITAL" is off.So it presumably only supports PCM over S/PDIF.

I see the d1 has usb input. i don't have a sound card in my pc, do i still need to get one if i get d1 to improve the sound quality? thanks.

The D1 functions as a soundcard, so no, you do not need another sound card. Plug the D1 into the USB port on your computer, and an amplifier or headphones into the D1, and enjoy your music!
