Newbie here, sorry for n00bish question, but I want to done this mod on SBLive! 5.1 but some question:

1) Is it worth it?
2) Which one should I replace with LM4562?
3) There are three power filter right next to DSP chip (I believe), do I need to replace all three?

The only mod I've done is wrapping the card with antistatic bag to reduce EMI, but I can hear audible sound difference from this mod alone!
Here's a pic of my card (SBLive! 5.1 Digital SB0220)

this thread is specifically for the x-fi. You will need to start a new thread with your questions for the SBLive. Try the DIY section. the op-amp may work, but you'll have to research the op-amp that is currently used and make sure the pinout is the same.

Did you guys confirm removing the four caps near each opamp?

What do you recommend: replacing them with better caps or save money by just shorting them or no need to short them , which option is worth ?
post #486 of 2194
the non-polarized caps can go either way.. there is no +/- correct?

That's the reason why they are called non-polarized.

soloz2, I sent you a pm regarding buying a pre-modded card from you.

Thank you in advance for your time.

I wont recommend anyone to do this mod since we dumb ****s are not frickin electronic engineers ! We are not 100% sure what the mod even does..

Meh my card is like 2 years old now, I cant really lose anything by modding it. If I screw it up Ill just buy a better card. But if I do it right, and it doesnt seem too hard, oh and I already have the blackgate at home (so i can mod this weeked) and 3 of the op amps, gonna have to order 1 more this week, since Im gonna be using surround. But if it makes a huge difference its gonna be just like getting a new card.

Well apart from the shorting of capacitors (which i decided against) its just replacing parts with better quality parts.

Having said that I do have a problem with my X-Fi, even though I'm not sure if it's due to the mod or not.. I posted it in the soundcard forum already but I'm curious if any other modders have experienced something similar, or has an explanation.

http://www.head-fi.org/forums/showth...66#post2898266

Please have a read and post any ideas either here or there, thanks.

My exact mod was:
- 1000uF 25v nonpolar Blackgate in place of the 220uF 16v jamicon
- 4x22uF 16v regular Blackgates instead of same rated jamicons at the decoupling position
- 1xLM4562 opamp instead of whatever there was on L+R before

the only thing potentially 'wrong' about this i can think of is that I modified the L+R opamp and caps but not the surround ones. But that didnt seem to be a problem for others.

The soundquality when running is flawless (and absolutely breathtaking) and I still do not exclude other causes (i had some odd ASIO things happen, problem is i modded the card the day after I got it, so I'm not sure if it started after the mod or not)

I think you mean 22uF, as there are no 4x 220uF to be found on the board.
The other opamps have nothing to do with the opamp you replaced. They're all on separate signal paths, so you can replace them more or less at will.

yeah 22uF for the decoupling caps, sorry, Ill correct the post above to prevent confusion.
And yeah i agree theres no real reason why replacing one path and not the others should be a problem, that i can think of. Im really not sure where to search the cause for this one, if one of the capacitors or the lm4562 was somehow not working then I assume there would be problems with the sound aswell which there isnt at all.

It's working ! I did the opamp, blackgate, and ERS paper on it. Wow, this sounds very good so far- a huge improvement from the sterile sound of how the x-fi used to sound. I'm guessing I'll have to burn it in a while before I can tell, but so far so good .

Edit for stupidity- Oops, we have a problem! Although it did sound quite good , there was something about it that was bothering me. I finally noticed that my right side is getting significantly more volume than my left (I'm slow on these things... :P). I was able to work this out by ear by using a channel test alongside an equalizer- which is working for the time being. Yet, I kind of find this unsettling and I was wondering if anyone had any suggestions on things to check for this.

It looks like the bad news about this mod is starting to come in

It could be that the power capacitor still needs to settle in a bit before it can give reliable output, but as you can see above and in the other thread i started about it, you're not the only one who has problems of one kind or another after applying this mod.
I have some serious reservations now in advising people to apply this mod - the results seem too unpredictable.
