I'm an absolute novice with computer audio (and really all audio for that matter). I've recently begun researching high quality headphones. That search inevitably lead me to discover the need and advantages of headphone amplifiers and dedicated DACs. The Schiit Magni + Modi combination is looking good to me, perhaps paired with the HD598 headphones. I've learned a lot in my research, but there are a couple concepts I'm still hazy on. Hopefully you guys can straighten me out.
1. Aside from hooking my Modi into the computer's USB input and selecting it as the output method, is there anything else I'll need to do to bypass my computer's onboard DAC and ensure the Modi's doing all the work? And how do I actually verify that the onboard DAC is being bypassed? I'm running Linux Mint 16. Sound card is integrated (ASRock Z77 Extreme4 motherboard).
And the concept that I'm most confused about:
2. "Bit perfect". What exactly is it, and is it something I should care about? Will the quality of my music suffer if I neglect this? I'll be listening to CDs and FLACs.
