I spend alot of time listening to music and playing games on my computer, and I'm becoming a head phone nut... My current headphones are Beyerdynamic DT660's which have ~30 Ohm impedance and thus no need for an amplifier; however, I'd like to experiment with higher end headphones in the future. And as a headphone user I'd rather pay for a single great DAC (stereo) rather than 4 good DAC's (7.1 channel surround).
I wish Asus would use the Burr Brown PCM1792 DAC (132Db SNR, $14.55) rather than the PCM1792A (127Db SNR, $13.35). Or even make the DAC swappable like the opamps are. On a card obviously aiming to provide the best stereo quality, saving $1.20 on the DAC just doesn't make sense - for comparison the "second best" Xonar D2 uses four Burr Brown PCM1796 DAC's (123Db SNR, $3.70 each). |
They are using the DAC they could source, there was issue with the other as it is being dis-continued or something of this nature. They are usign the best DAC avialable to them. The D2 would use a DAC with 123dB SNR but in normal practice the D2 would never even hit 120db SNR. The supporting ciruitry isn't up to the task.
