Really? According most the members here the card is great. I find no source will please everybody and it depends on what else your using for gear.
I can quote the multiple pages of gushing praise you wrote on this card.
Here allow me:

There is many more in these threads just like this.

turning off the computer every 15 mins is also an option.

I was wrong about STX, I was using the 64-300 ohms setting for my HD580. I should have used the 300-600ohms setting and played with the volume control.

Which seems to be a reoccuring issue. People not setting the card up properly.
People either setting the gain too low or to high and complaining it is fatiguing--well yeah, way too much gain!

Glad you got it figured out. You can also swap out the opamp to tune more to your liking.

Im using 64-300ohm for 300ohm hd800's and the volume is set to 3 when i want to relax and 6 when i want it loud

 

[KingFiercer]

I'm using 64-600 gain too with my HD 600 - 12 relax, 24 normal, 40 heavy music.
24% with 64-600 equivalently 100% with 0-64, and I want to note that is more transparent sound with a lightweight bass = more details and space. I like 0-64 at night with still music (not only

).
300-600 gain makes bass overloaded and treble less soft.

HD800 with STX sounding good enough? =) You're using stock amps?

check out the HD800 impedance vs. frequency chart, it even jump above 600ohms in mid range, that headphone is a monster!

Use the setting which I'm using:

-300-600ohms
-use xonar software like preamp and set the volume there at 50%
-use foobar to control the volume

you're using the 300-600ohms setting using xonar software as volume control. that means you can only listen to 10% or more... Use xonar software as preamp and set the volume at 50% or more. use foobar to control the volume.

You are doing your HD800 some SERIOUS injustice only amping them with the STX.

only if you get someone w/ an oscilloscope to check whether they're not oscillating...you really don't wanna ruin your HD800, do you?

rolling opamps blindly will not work on pesky non-unity gain stable opamps...it just won't.

and those that are easy to roll sound like **** anyway...LME49720/OPA2132/5532/2114/etc etc.

the HD800 is said to be hard to drive...it's a disgrace to run it from the $2 TI HP amp IC that's on the stx...the day you'll shell out $500 or so on a real headamp, you will be amazed...don't believe the hype.

You may want to just use the AD797 for a buffer. If you use the same model for both I/V and buffer the "negative" aspects of the sound signature can compound. Many STX/ST users use it for the DAC quality and not so much for the headphone amplifier. Possibly a nice tube amplifer using the STX DAC with some high quality opamps?

 

[Duskfall]

Any updates for the opamps?I am newb to this section of modding cards so i have ordered 5x LME49720 since i can get them free .I love bass and clear sound.Using Sennheiser HD 555.
I want to use them for headphones aparently,so shall i only put 2 to I/V or shall i also try to buffer?Also other Opamp recommendations are welcome

 

[ROBSCIX]

If your using the headphones amplifer you only have to change the I/V opamp pair. The buffer opamps is used only for the line output.
Make sure you order LME49720NA, the NA - DIP8...any other model and you will have to use adapters. Many liek the HA models but you have to use adapters with them but TO-99 metal can opamps are usually the highest grade of any opamp family.
Good luck on your tests.
