Can I ask why you chose a 2200uF standard Blackgate? Why not a 3300 or 4700uF? These are also available for 16V.

probibly no benefit/ cost outlay.
2200uF is a lot of capacitance, and its being fed DC power, which in theory should be relativly clean with modern switching transistors and vregs etc.
the massive HT amps normally have 2x 33000 uF capactiors running maybe 8x170w DIN or whatever, so 2200uF is already overkill imo

yes Gilly is right the 2200uF is already overkill.
a 4700uF Blackgate would be enormous and cost more! the general practice is to use something that is 10x the original value. any more than that will probably not yield any improvement. most people use the card with an amp which has a ton of capacitance, so actually with an amp the original value of 220uF is already enough. However, Blackgates have much better specs than Jamicon so the capacitor should still be replaced. I just picked the larger value because for some headphones I don't use a dedicated amp.
btw, there are other good choices for capacitor besides Blackgates, to those who care about every dollar in their wallet. Just be sure to not use too high voltage ratings, since electrolytic capacitors work best near their voltage rating. Thus we would use a 16V capacitor for 10-16V.

Thanks a lot Gilly and cotdt. You've convinced me. I'll be upgrading the capacitor too.

The U.S. Sites I emailed in this thread about purchasing ERS paper and a capacitor, gave no response yet :S. Can Radio-shack order this for me or possibly can I buy a similar Capacitor and ERS paper at Radioshack?
Thanks,

alright, I finish half of my mod....
I only changed the OPamp
waiting for the capacitor and ERS paper
the problem is.. right after I solder them in.... the sound is very small and it crack and pops 
Then after .... I test it three time, try to re solder the join every time....
finally, after removing some excess solder, I finally got the sound fixed'
wondering what cause it though
================================================== ==
after I changed the OPamp, I found that the highs are much more clear, and seems like there is a little more sound stage
well... the bass sounds little different.. but don't know how to describe it

I received my Xtrememusic today. I was expecting the opamp chip to come as well but it didn't so it looks like I have to wait a little longer to mod it.
For the best music settings with the Xtrememusic, I should just turn off all effects and put it on audio creation mode and turn on bit perfect playback, right? With this, there's no reason to use ASIO or any other settings through Foobar, is that correct?
I hope I get my opamp tomorrow

Is the 2200uF blackgate polar?

So do you line up the + on the blackgate to the white semi-circle on the X-Fi's PCB, or the unfilled semi-circle? Sorry, I'm not an electrical engineer...

YEs,i too get a reading of 2.45V DC.The 5V output of the regulator is split to +/- 2.5V to power up the opamps (which is why i replaced the JRC with a AD8620);both work very well with low voltages.
IMO,the JRC4556 is not a bad sounding opamp by any means,just slightly less detailed and airy and warmer.

How does the AD8620 compare against the LM4562 suggested by cotdt? It seems to be a lot more expensive, but it's also more easily available.
