Pm@c: try to keep this thread a bit compact for those who need to plow through it all before they do the mod (something you didnt do judging by your questions :P)

Yes, 9.77$ for 3 opamps is a fair deal.. some got theirs for free but most had to pay for it and often more then 9.77$.

PPkiller: doesnt really matter much. They're close together so you could just bridge it using tin if you have a little patience.. I used short bits of copper wire.

I'm using Vista so the driver issues are still troubling and SQ is not as good as in XP, but the modded card sounds slightly better then the unmodded card in XP. I'm sure as support grows I'll be able to get even better sound out of this card. For now I'm very pleased with the results. The noise floor is much lower, with better imaging and stereo separation. The soundstage is wider, so it should be even better for gaming. Bass is slightly more impactful as well. I'll have to wait for the caps to burn in of course, but for it sounds better from the get-go which is what I had hoped for.

I cannot comment on how much difference the Nichicon's made as I did that mod along with the Blackgate. Overall I think the largest difference was made with the new LM4562 op-amp.
I couldn't find the appropriate Nichicons from Digikey, so maybe I just order 22uF 25V Elna Silmic II's for the card. I already have 1000uF 25V Elna Silmic II waiting to be installed.

Edit: Oh, and what is the lead spacing and diameter for those 4 caps? Is the lead spacing 2,5mm and diameter 5,0mm or 6,3mm?

Sorry phlanger but I have another question. First off the primary mod is just the blackgate capacitor and the opamps right? Then cotdt mentioned a jamicon recap. What does that involve? What sort of values will I need, and exactly how many jamicons (and where are they) do I have to replace for a whole recap? What does the recap do for the card?

I believe that's the correct lead spacing, but I didn't measure. diamater 5.0mm will fit although it's slightly larger then the stock jamicons.

a whole recap is exactly what it sounds like... you replace every cap on the card. You take the values off the card itself and then buy all new caps, desolder the original caps and put new ones on.

You'll really only get better SQ with changing the caps that have been suggested. On top of the op-amp and blackgate I have suggested replacing the decoupling caps with some nichicon fg 22uf caps.
the rest of the caps will really just give the card more reliability. jamicons aren't known for lasting years and years...

Elna installed. I practiced desoldering on an old circuit board and it didn't work so great. Fortunately X-fi was much easier to desolder and solder and everything turned out good. Was a little bit scared if I ruin my card

First impressions: AKG K701 seems to have more bass and sounds great. Now some serious burn-in...

I know im a noob..

does it matter which lead you solder where? is it clearly marked?

Yes!!!! the op-amp has to be placed in the correct orientation. The caps are polar so you have to get them on the card correctly.

The good thing is that both the caps and op-amps are labeled. and the card is clearly labeled for the caps. op-amps not so much, but if you pay attention to the op-amp you take off and put the new one on the same way you're good to go.

I suggest you watch the tutorials on tangentsoft.net. Warren explains the way to tell which lead is negative and positive in an easy to understand way. I think he even talks about SOIC op-amps.

My Modded X-Fi Extreme music is on sale on Ebay. All 4 opamps has been replaced with LM4562.

Anybody want to do a group buy for the blackgate power filter? From my understanding, the total for 3 blackgates is $36. So, $12 a person. I just need 2 people so if you're interested give me a PM. Non-cc paypal only please

thanks...

hmm... is blackgate nx 1000uf 25v better then the blackgate std 2200uf 16v(in terms of SQ)?

p.s. i think i'm getting my 3 opamp for free..
post #463 of 2194
I tried this - unfortunately I seem to have pulled out the contact traces on the board when trying to remove the first opamp.

Guess it's buggered ;p
post #464 of 2194
cotdt,

what method do you recommend for desoldering the opamp?
post #465 of 2194
I ordered 22uF 25V Elna Silmic II's for replacing the caps near the op-amp. They are 6,3mm diameter so they are definately a little bit wider than the original caps. I think that they will fit just fine or with some little bending.
