If used as a line output, onboard audio on recently made motherboards can work well if the implementation is good enough. If not, then noise (interference from other parts of the computer) is the most common problem. If you did not hear a difference compared to the Titanium HD, then buying a more expensive external DAC is probably not worth it either.
What is line output? What about this? Is this line output?
one wonders how easily an ABX test of the available opamps could be successfully accomplished.
If you'd like to test your onboard solution you can use a M-M stereo headphone plug cable to do loopback testing with RMMA.Results can vary depending on sampling rate & word length; here you'd be limited by the ADC.
I'm using VIA VT2021 onboard and when compared to my previously owned Creative Sound Blaster X-Fi Titanium HD, there is no difference in quality. It's just the titanium HD sounds a bit louder than my onboard. What about you?There is this "DAC" thing like this:How is this compared to today's onboard audio?
