ok, just to confirm then, here's what I've taken that to mean and I've used paint to dot the 16 caps which I think are the ones to short.

(note, I haven't physically taken my card out to see which ones are 22uF ones yet)

Hi, is the caps with red dots the exact caps I need to short for elite pro? if yes, I'll mod short this way.

Another question, which is the line-in op? I'm doing recordings, so I want to replace it with LM4562 too, thanks!!

How would you remove the stock op amp if you don't have micro side cutters? Sorry if this has already been answered.

you can get copper wick and suck up all the solder. or... just add a huge amount of solder, turn the solder iron to max temperature, and lift the opamp out of the molten solder with a tweezer. there are also other ways.

Thanks for the advice. I just ended up using small scissors. This mod if awesome and practically free, two thumbs up cotdt.

Would it be possible to zapfilter this? Run the DAC signals out an empty bay in the back and mount the zapfilter in a box on the desk? Not that I would seriously do it, but just curious.

of course you can, but such a mod would be more involved than just swapping out the opamp. there are also certain opamps with better specs than the LM4562 that can be used, but they require a different voltage and not just a direct-swap in. alternatively, you can also use a transformer-based output. there are many, many ways to do it.

OMG, i am doing this with my fata1ity pro (with the breakout). I am so glad i didn't get the elite pro now (because i am replacing opamps anyways). For those wondering, the only reason i got the x-fi was that it was on sale at Fry's electronics for (cannot display price, too low, people might kill. lol, jk, twas $50). thats right, i got it for more than 75% off. double rebatage FTW.

I can't wait to do this mod, does anybody know how much those opamps cost?

*looks at ****** old soldering iron* aww, crap, i hope i don't fry the thing.

wow, that was a nice deal. the opamps are free if you order samples for your "company". if you have a university email address, they'll even give you free shipping. the first post of this thread has all the details.

I think im terribly blind. I read the first post several times over, and i don't see anything about ordering.

ALso, i may be 16, but i have a stanford.edu email hehe (free shipping) (i am going there for summer school, lol)

You can request free samples here:

Study some physics, it really pays off in this hobby

I got this instead: http://www.national.com/pf/LM/LME49860.html
it's the same thing right? (i ordered 5 free samples b4 you posted)

Also, do i need to put these in the breakout box (not the elite pro one, but the fata1ity one that goes in the drive bay) as well if i am using the headphone port in the front? Are there any capacitors in the breakout box that need to be changed.

Alright, I've got a question.

I tried the mod, and I screwed it up. I tore one of the pads off when I took the old chip off, and I also tore one of the nearby traces. I had someone try to fix it for me, and they did a great job, but there's a lot of noise coming from the right speaker, and it's very quiet.

So, my quesiton is this: If I buy the I/O drive kit, would that fix my problem? The only thing I tried modding was the opamp, does the drive kit have it's own opamp?

I did the same thing, but was able to fix it. The traces that go directly to the op amp are very short, remove the old one and trace the via (alternate word for trace on pcb) back to where it meets a surface mount component. Take a couple thin strands of stranded wire and solder it to the sm part. then carefully bend the wires around so that they meet the input pin on the op amp where its missing the trace. Then cut the wire to the proper length and solder down. I covered my op amp in hot glue so that the wire wouldn't go anywhere. Also make sure you don't short the signal wire to any other pin on the op amp.

I bought the X-fi platinum because it was $80 bucks after rebate but the front i/o box muddles sound a bit. Either that, or the op amp mod really changed the sound quality.
