Xonar X3? assuming you mean Xonar U3, the $40 Xonar USB sound card?
And you using a 3.5mm (1/8") plug to 3.5mm plug cable to connect the U3 to the Bose?
The Xonar U3 should have automatically become the default audio device, when you plugged it into the computer (and installed the Asus software).
The Xonar U3 control panel should have the output set to "Speaker"
and as I'm assuming this setup is for music, the Xonar control panel's Audio channel should be set to "2-channels".
Should not need to have the "digital output" enabled (leave disabled).

It's the U3 yes. Can I not play the music from the U3 playing on my Bose, which then the Bose can be heard on my laptop speakers?

When playing my Xonar U3 through my Bose Soundlink Mini, what should my 'SPDIF' settings be? Unticked/Ticked PCM
 
Thanks

Assuming your connecting the U3 to the Bose using an analog cable (and not optical), leave the S/PDIF unchecked (unticked).

It's been a while since I used my essence. Does anyone still have the problem where it suddenly screeches very loudly? I had to stop using it for fear of damaging my stuff as well as myself, but it's been over a year so I'm hoping there might have been progress on that front.

  Isn't the Sound Blaster ZxR or X7 is better than the Asus Xonar Essence STX?

 
All three use DAC chips from the PCM179X series, so audio quality should be around the same.
All the use the same TI 6102A2 headphone amplifier chip.

Oh I see, thx for the headup.  The X7 is the newest and latest from Creative, but to my surprise they still use the same DAC quality as like 5years ago since the STX and ZxR came out around that time ago.

Can anyone recommend a good opamp combination for DT990 Pro 250 OHM? Money isn't an issue. Currently running 2xLME49720 with stock buffer. I've always used the headphone out so the buffer never mattered, but now that I've switched the sound is very displeasing... It lost a lot of bass. I also just upgraded the opamp in my LD+1 to a MUSES 02 so that may have added to the loss in bass.

AD8066AR has excellent bass, although I doubt it will make up enough bass if your lacking... http://www.ebay.ca/itm/1x-AD8066AR-SOIC-TO-DIP-High-Performance-145-MHz-FastFET-Op-Am-/120885159736?pt=LH_DefaultDomain_0&hash=item1c25512738
 
I use it in the buffer, along with some OPA627BM's in the I/V. I find this combination is very balanced/neutral, with great overall sound in all areas of the spectrum.

Any experience using 2x LME49720NA + LM6172IN?
