Hotrodding the X-Fi: A Layman's Guide (No 56k) - Page 133

I just use one single capacitor on the output and removed the resistor because there is already resistor after CS4398 and before the caps. It sounded very good, makes me wonder why do they need to put opamp after the DAC? Its a voltage out DAC and doesn't need one, and sounded natural and distortion free

I have a creative x-fi extreeme gamer it is the smalller one
I am looking for someone to mod it for me with the works
I am an avid online sim racer and looking for the best sound i can get in surround sound

please recommend and give me details as far as cost ect.


Thankyou

I have an Xfi Xtreme Audio PCIe SB1040 (yes the crappy one) and changed the OP Amps. Difference was night and day. However for the rear channel i took off a solder strip for one of the legs so the rear black jack doesn't work. The other ones are fine though. Is there anyway to remap the jacks? I'm using YouP PAX with Win7 64bit with the summer pack. Or if anyone seen schemas for the Xaudio (it's pretty diff from the real xfi) i might be able to hot wire it somewhere. Thanks!

I have the same symptom, I soldering lm4562 (in front) replace 4556 and get that symptom, I think maybe I burn them with solder, order new solder them with much carry on but the same symptom, then first ("burned lm4562") put on the rear change 4558 result front same symptom rear work left right but volume is low and causes unstable froze the comp etc....then I put back 4556 on her place and work but with unstable system and I take off rear ("burned lm4562") and now work fine without rear chip on....

Now is mess with the layout and I pay too much (for one lm4562 12Euro with post, yes, yes I know but that the way is here...) and for now I stay with this project...

What you think do I burn them 2 IC ((lm4562) 4556 solder and desolder several times but work) this is not my first work I have experience with soldering but with SMD little (I know that they are sensitive and I fast solder it but...(temp of solder was about 300c) or incorrect IC (hmmm I seen that too, wrong legs...) or my non seen problem with broken or short circuit layout (but I watch and check circuit)

After reading the guide and asking for a friend's advice whether to do it or not, I finally ordered 4 LM4562. I short circuited the four caps and replaced the Jamicon 220uF/16v with Elna 2200uF/16v (I didn't find Blackgate, is Elna good?) and it sounds much more better than before. I'm looking forward for receiving those LM's. Hope I keep things clean as I did until now and don't mess anything up.

I'm in the middle of upgrading my Xtreme Music with new opamps and capacitors. Unfortunately I've learnt the hard way how fragile the solder pads are on these things and have managed to rip two of them off. One is for the mic opamp and I just can't seem to trace what it's supposed to be connected to. If anyone knows or if anyone with an untouched card could look into it I'd greatly appreciate it.

Seems like it's my lucky day. According to this that pin on the opamp is left open which, unless I've misinterpreted it, means it's not connected to anything.

Yep

Output, Out2, is left open. (to insure opamp current demand is minimal)

and just to say, all I have done is shorted the caps, no opamp or capacitor change yet, it does sound a little sharper

Hey,

I recently replaced the op-amp on my x-fi xtreme music to the AD8599 and the power cap to a 16v 1000uF blackgate, but there is a problem. When I am listening to music, the volumes in both the L and R channels are very low with windows volume at max. I guess its like a 50% loss of volume? Anyone know the problem?

sounds like the opamp isnt getting enough power. but wouldnt like to pinpoint the exact fault (sorry).

does the power filter capacitor take all the input power and supply it to the card? reason I am asking is, if its the wrong way around, would the card exhibit similar problems to those Dhw4488 is describing?

I'm not an expert on this, and havent look at the traces, schematics or specifications.

Nevermind, I figured out what the problem was. It seems part of the AD8599 v- pin was somehow cut off even though I did not do anything like that. I just added more solder to connect that joint and it now works out perfectly.

Hi all
this is my audigy live value 7.1 mod
i only use it as transport to my external DAC so this is what i did.

1. replace the caps for i/o lm1117 regurator ( digital part )
2. remove some smd caps
3. add RCA and rewire to the sorce of SPDIF signal
4. driver mod
5. i did some caps mod for analog but didn't use it at all





The result was grate. all the detail, bass, cleaness have improve.
i send one to my friend, he said the SQ comparable to his auzentech prelude and the bass is better.

next week i will try X-fi Xtreame fidelity (sb0790) with mundorf m-lytic cap. will let u all know the result.

Nicely done mz5 When your friend say its better than Prelude, do you mean its analog stage? Looks like it uses Wolfson DAC instead of Cirrus Logic on regular X-Fi cards, can you tell me which one is it?

Apocalypsee

i mean the spdif out is comparable to prelude with deeper bass and better dynamic .

the audigy has no way to go close to prelude on analog stage

i will mod x-fi for analog and send my friend the card to campare angain



this is the x-fi that i am waiting for some part. will use m-lytic and polystylene for this card. do you have any suggestion for this card?
what opamp whould be the best for it ? (for audiophile)

and has anyone mod power supply yet ? any thread for it ?

Thanks

Oh the SPDIF, I thought the analog out For opamp, there is lots of choices, I recommend LME49722, AD8599 (some say this sound 'analog') or LT1364
