STX isn't good card according to data sheets
PCM1792A THD+N at 192 kHz: 0.0015%
TPA6120A2 THD+N at 32 Ohm: 0.00055%
JRC2114 THD: 0.0005 %%
It has high distortion at 32 Ohm according to Xbit labs
Two in One: Asus Xonar Essence STX Sound Card Review (page 7) - X-bit labs
|When I had been listening to the Auzen X-Fi Prelude, I had not expected any card to surpass it. Later on, the ASUS Xonar D2 showed the weak aspects of the Prelude. And now, the Xonar Essence STX sounds better than the Xonar D2 and Prelude, and better than the X-Fi Elite Pro, and perhaps even better than any audio card in the world, but I still want some more! It is a shame that the Essence is just one step short of being perfect. It just needs better resistors and different operation amplifiers.|
The saga of the fluttering volume continues--it came back the day after getting the replacement card. So I wanted to report back that it's at least not a problem with the STX. I've got another PSU on the way and if it's not that then I dunno...maybe it could be the motherboard? Very strange.
good thing for you if can hear a difference between 0.0015% and 0.0025% THD.
