Gramophone

Now that I understand better what a DAC is and does, it seems almost certain that my uncle doesn't already have one. The computer will be very low grade, including the motherboard, which hosts the audio chip. I belatedly understand now that the goal is to convert sound from digital to analog and have it bypass the motherboard's audio chip. (I know computers well, but sound is unknown territory to me, beyond plugging the speaker's little plug in the green circle.) I don't understand this part. If the DAC bypasses the computer's audio chip, why would the computer change whether those greater options make sense? Or do these other options work differently? As for the type of files to be played, it would be simple and common: FLAC and mp3 with bit rates that any device can play. I am waiting for him to call me back, so I don't have more information yet. Thank you both for your answers.

Hello! Now that we are in 2015, PCs are becoming somewhat common in households. It helps that they no longer catch fire or inadvertently send taunting messages to other planets. For these reasons, among others, my uncle wants his very first computer. He is an audiophile and this is a call for help to his brethen. The question is, what should I do to hook the computer to his sound system? Should I simply take the plug that goes in the CD player, put it in a Y-jack, and have that plugged straight into the computer's motherboard? Should I get a soundcard? I'm looking for good possible solutions for under or around 100 $, because listening to music is not his reason for getting a computer, yet I still want his computer to take advantage of his good sound system as much as possible without his wallet noticing. There's always room for upgrades later if he wants to. I don't know what gear he has, but I do know that he has spent several thousands of dollars in his sound system over the years. What does that include besides the speakers and CD player? I don't know, but I would not be surprised if he has some more things hooked inbetween. He probably doesn't use headphones, and having never learned to appreciate the wonderful subtleties of dubstep, he is more of a recorded concerts, jazz and classical music kind of guy. To my understanding, a PC->DAC->Speakers system seems to be seen as good. If he does not already have a DAC, would it give better results than a simple adapter, considering his musical preferences? Is there a reason I should favor a soundcard over a DAC or vice versa?
