Hi, a new  Nu Audio user here and just joining in the forum, looks like Burson V5i is a good deal for replacing the OP Amp for Nu Audio, just curious is it okay to replace both OP Amp with Burson Audio V5i?
Sorry for my poor english :)

Yes! I just did that a couple weeks ago and they sound amazing! Although, the stock OP-AMPs didn't sound all that bad either. :)

Does the NU Audio Pro card have any circuit protection if ever we accidentally put any op-amp in the opposite direction?

Mostly what I've been told is that the op-amp would likely be toast, but the card would be unlikely to be affected.  Fortunately, it's pretty easy to put the the op-amp in the correct direction, so I wouldn't worry too much about it.

Great! Then we are all assured that the card won't get damaged if that ever happens 

I recently upgraded from some DT 990 Pro, to some AT R70x headphones, and decided to explore the OP Amp suggestions.

I went the route of the TI OPA2228, replacing both stock amps. They BUMP and it really does sound crisp to my ear, after some suggested EQ for the phones, i honestly could have stopped there.

I also ordered the TI OP828 on the browndog adaptor ( from cimarron tech. Its a single channel amp, so the board is required to use in the cound card. ) I may have botched my listening test the first go.

So currently, i have the OP828 as a Line-out / headphone Pre Amp and the OP2228 as the headphone amp. 

The 2228 is better at driving my headphones, and it feels like the 828 fills in the detail. Ive only had this combo for hours now.

That's a nice and elegant solution.  I will make sure we consider something like this if/when we return to audio products.

Does anyone know if its ok to put the shroud back on after installing a sparkos SS3602?  The shroud will fit, but it does look like the back of the shroud is touching the top of the exposed opamp.  If its not touching then there's about a hair's width clearance but from as close as I can see the shroud will be touching it if I put it back on.  Is there some thermal padding or something I can use to put in between the shroud and opamp?

See my post above, but I have the sparkos SS3602 installed as well.  I made a spacer to have the shroud offset from the card to allow space for the op amp to clear the card.  I also put some kapton tape on the underside of the shroud in case it did make contact.  Before I made the spacer I just bought some 14mm long M2 machine screws and nuts and offset the shroud from the card.

I dont think I can do the 3D printed part but I could do the kapton tape part.  I assume its a non conductive tape?  Guess I could look it up lol.  The shroud does look like it'll go back on, but I havent tried to screw it back on for fear of messing up the opamp if it is touching.
I found it on amazon, will this work to underline the shield with?

It was a little to close for my liking without the space.  So yah, kapton is electrically insulating:
 
Kapton tape is usually used in electronic manufacturing as an insulation and protection layer on electrostatic-sensitive and fragile components.
 
Before I made the spacer, I just used longer bolts and put a nut on the underside of the card to keep the bolt snug:

So would the kapton tape work to prevent any shorts if I was able to get the cover back on?

Is it me? a driver bug on windows 11? or a faulty card? I started noticing it upon turning on my pc. Things sound fine, and sometimes after restarting the system or at some point in the day, the sound becomes muddy when watching a youtube video or playing music. The bass becomes muddy or the center frequency and it affects the voice on videos and afterward, any music sounded muddy. When that happens, my hint is  I open the control panel and switch the surround On and Off and nothing happens. I will know if it's back to normal because the surround function works. But I prefer to turn off my surround, it's just for checking if it will start to sound muddy.

What OP-amp(s) did you roll to?

It doesn't matter, I went back to stock but the same result. 
 
I also saw someone comment with the same card as me (Nu Audio Pro) on this reddit page:  www.reddit.com/r/Windows11/comments/o9vhqp/does_anybody_know_what_the_enhance_audio_setting/
 
Windows 11 Enhance audio setting is off by default after installing the driver and every time the PC is powered on, I get the result I posted. But now I left the Enhance Audio on, the problem goes away but the sound signature seems to lean more on digital. It doesn't sound more on the analog to my ears.

I was wondering because this is a thread about rolling op-amps.
Yes, you need Enhance Audio on in order to use the audio effects.
No problems here on Win11.

I do have the v5i, muses 01, muses02, and sparkos labs ss3602. I am not using any effects though, that's why I left enhance audio off, which leads to hit and miss on audio quality upon starting up the pc. Now I left the enhance audio turned on with surround off on the evga control panel.

 Opened the door to my question. Do you know of a good source of good reliable Op-Amps (NOT Knockoffs). and yes often a different manufacturer of the same unit number might not sound as good as another.
I would love a source list for any of these and known features good/bad.
