Looks like you bent the caps, i may try this on the headphone out
 
but it really doesn't look like there's much room around either op amps

When I removed the shield from the card I went, "Wow, that's a lot of bent caps."

 
Yes I know, that's the wrong direction to put the Op-Amp.

What's the X4 (clock) value?
 
Also, why this thing is limited to 384 if the AKM is able to do 768kHz@32-bit with no problem?
 
The IC also supports DSD512 (22.4MHz).

From our own testing, the card can use 768kHz @32-bit, but the XMOS chip would force us to disable EQ at that sample rate.  Coupled with the extremely limited amount of content currently that is available at 768kHz, as well as no DAWs that support that sample rate for recording, we made the choice to keep it at 384kHz.  

 Well I gave it a try and yes it does work. Unlike replacing the headphone Op-Amp, I'm not sure if I heard that much more of a difference in either headphone or speaker output this time.

So i have been on the fence about getting the V6 op-amps this week, spent my money on more headphones heh. So after this mod you can 
definitively say that the Bursons will make a 20 dollar headphone set sound like they are Focal Clears, would there be any other advantages you immediately noticed?
Or what im really asking is would you recommend the Burson V6's

Should you have the $70 USD and shipping costs, I would. I don't know anything that would make cheap headphones sound like Focal Clears though, lol. You don't have to buy two, just pick one and then decide if you use the speaker output or headphone output more and go with that. 

DSD audio is quite dead on arrival . The lack of titles and the size of the files make this format somewhat undesired. I have an asus essence stx with OPA2134PA-ND op-amp SoundPlus series DSD over PCM + Sennheiser HD 700 Headphones. DSD is great but not many people are really equipped to hear the difference . DSD 256 files are way too large. A normal CD 16 bit 44kHz-WAV 630MB would be DSD64 2.5GB , DSD256 9.8GB or 192kHz-FLAC 2.7GB...what I mostly use is FLAC 1.2GB or PCM 48hz AIFF 1.7GB .
 
Most Gamers don't listen to very high quality DSD audio files for the main reason that DSD files are classical or jazz music.  Anyone can listen and make their own mind as if they can hear the difference between a FLAC file or AAC 320 , go to radioparadise.com/listen/stream-links , you can then test their flac player link and listen for yourself.  Then you can go to 2l.no/hires/index and download some sample files in DSD, MQA, or whatever you want to test, if you're equipped to test those files. Use the AAC320 url link in foobar2000 and ASIO output if you can. If the words ASIO and foobar wasapi output doesn't mean much to you, then DSD won't mean much neither. 
 
A great stereo sound card will position the sound like a 5.1 system if you have a good set of headphone. The problem being that if you use a normal set of gaming headphone/microphone , they are usually not of a super great quality. If you buy a $250 sound card, you need at least a set of headphone of equal value. Nobody will convince me that onboard sound is equal to a good sound card like that new EVGA NU or older Asus essence STX except for some $500 EVGA motherboard that have the Creative Sound Core3D Quad-Core Audio Processor, which are very good. Many of the features needed to produce clear, crisp sound simply can't be added to a Realtek onboard sound cards. Those Realtek chip don't perform like a ESS sabre or AKM chip. ( the OPA2134PA-ND op-amp SoundPlus series is very good, much better than the OP amp that came with the essence stx ,I've tried 4 different op-amps and this one is the best ) The older asus essence stx (or STXII) 7.1 is really hard to beat for gaming and audiophile sound.
My 2 cents. ! 
 

Yes, upsampling to DSD512 is extremely nice.  Which is why it is a bummer that the potential of the AKM was kneecapped.

Please. Having support for dsd512 would be extremely welcome!

Since I don't use my front audio connectors I don't have to connect the HD Audio cable to the card if I don't want to correct? Im mostly using the card for my AudioEngine Speakers. My gaming headset is usb. 
 
Just want to make sure 

The front audio header connection is optional.

I was wondering does the EVGA software allow the audio responsive LED lighting to sync with other EVGA hardware? I would love it if my CLC and graphics card and case fans in my DG7 would flash to the sound of the beat as well as the NU Audio card.

Not seeing this with PX1 or PXOC ATM.

Both are currently $199 the Nu Audio and the Burson Play what do you guys think out of the box is the better sounding and better deal?

I have SACD and high res. FLAC albums in surround. Are you planning to release a 5.1 or 7.1 version of this card?

Unless you have the super rare SACD capable disc drive that was released by Sony in the 2000s, no SACD can be played on a computer. To get the DSD files off of an SACD, both multichannel and stereo gotta use the PS3 Other OS extraction method.

But if you do indeed have DSD files on your computer, as I do, the card will output the stereo DSF files via the stereo analog outs just fine. You won't be able to output any form of lossless multichannel via the Toslink out, including DSD and your lossless FLACs. Although the lack of multichannel analog outs is a limitation, the need for such connections is such a fringe case to the point where I don't blame EVGA for not including them. Not many people have lossless multichannel audio on their computer, and even fewer will use their PCs to drive their playback.

I'm using Foobar2000 to play SACD ripped ISOs with either stereo or surround SACD tracks using 352800 Hz setting. I'm currently using Sound Blaster AE-5, which works fine for music and surround gaming. I'm really hoping EVGA releases 5.1ch version of NU Audio with native DSD support in mind.
 

I am an EVGA Elite Member, but I do not see a link anywhere to purchase a Nu Audio card. Can anyone help me with that?

Utterly pointless.  For stereo, you will never need anything more than 44.1 kHz at 24 bit (0 Hz to 22 kHz audio range with 0 to 144 dB [worst case] dynamic range). And realistically, usually 44.1 kHz at 16 bit is sufficient (0 Hz to 22 kHz audio range with 0 to 96 dB [worst case] dynamic range). Keep it real. Keep it compatible.

Have you even tried dsd upsampling. The evga Delta sigma dac upsamples pcm to dsd prior to processing. If you do this in the computer then you have more control and put less overhead on the dac resulting in layinga more natural sound. Try it!
 
If you want a natural pcm playback then get a r2r dac.

Pointless. Upsampling has no benefit. There was no useful signal missing from the original 44.1 kHz data stream.  And, up-sampling can't add supposedly missing natural sound to the data.  All up-sampling does is stretch out the data points and add nothing in between.  It's the equivalent of zooming into a pixelated image.  Plus, the dsd is single-bit? Why would you want that? It sounds worse.  And, why would the DAC ever need less overhead? Bunch of nonsense. Sounds like you were converting just for the sake of converting.

I appreciate your frankness but please just try it and I think you will be impressed. Your i7 3770k should be able to handle DSD256 upsampling. You can always use Foobar which doesn't cost anything. And note the upsampling algorithms are a lot more than just a linear interpolation with the result the music is smoother and more natural sounding. There are a lot of forums on the web supporting the value of this process.
