I am looking for a budget DAC around the $100 range to see if there's any real improvement to my computers audio which outputs through a surround sound adapter currently. Doing some frequency tests I've discovered said surround sound adapter, is malfunctioning and buzzing at certain frequencies where it does not when that feature is bypassed. So I am looking for an upgrade to PC audio. So, Is a DAC going to make me think "wow, this audio sounds like it's fuller, and with more depth?" Because onboard audio, or my surround sound adapter with the stereo pass-through function on sounds like complete garbage. Voices sound fake, artificial, quiet, they just sound more like a voice you'd hear on an old radio than in real life and I would like to know if a DAC is going to be a noticeable difference here. Second question I have is whether BALANCED audio is going to make a big difference here as well. I wouldn't mind trying it out, but is it going to be a mind blowing experience or am I just paying extra for "meh"? Currenly I am looking at the Fiio K3, but if balanced isn't going to be a noticeable difference, perhaps there is a better sounding non-balanced DAC in the price range? Portability is NOT a concern, this will be a permanent part of my desk.
