DIP, i see. Thanks for the wish, most of my important subjects already passed, so now can relax a bit.

okay, so i get a DIP socket, 62-36-2% eutectic lead and a good sucker! solder sucker i mean ;pp dont think so farrr...

I did some moddings to my sound card yesterday night, i pencil-mod my card and it made alot of difference. There was a slot for a cap in my card that was not used, so i took a pencil and draw a line across the two contacts and went to test it. The sound was much clearer, i guess its more voltage or something, not so sure. I saw many other forums that user that mod sound card, they take out the caps near the opamp and just connect the circut with solder. Some others got decouple the caps (shorting),same thing lah i think. I also did an EMI shield, but it made the sound very warm, which was good on IEMs but not so good on M3400, as M3400 is already a VERY warm sounding speaker...

I'm gonna start off with the sound card first, hope to get it done this weekend, so that next week can start on the speaker. This is my thread on the Soundcard : http://forum.lowyat.net/topic/1036526

also, any recommendation of op amps that are good to use on the speaker?

wat about mod a AD8620 on the x-fi....
good sound...but with a "good" price too...
recommend u pair the opamp of the sound card and speaker...
mean that a neutral opamp + a warmer opamp to avoid the sound become too warm...
for me, i will be place a lm4562/ad712/ad827 in the speaker while a warmer opamp like OP275/OPA2604 on the sound card...
or interchange them...
or, u can do the better setup >>> OPA2604/2132/2134/627 on speaker while AD8620 on the sound card...
the coupling caps on the sound card may be make it more neutral by using nichicon or blackgate too..

confuse?
i tot the sw is the bass oredi.
then how to set the subwoofer to 2 ?

i suggest ur C3, u set treble at 0 and SW to 9.

It's separate thingy, the SW=subwoofer, if you set it to 0, that means the bass of the SW will be weak. if you set the SW to 8 but the bass to 0, the bass of subwoofer will increase but still weak, the bass of satellite speakers will be weak, but if you set the bass to +2/4 and the SW to +6/8 both the bass of the subwoofer and satellite speakers will be strong.

AD8620 will be overkill for M3400 i think. Unless u have high clarity speaker like C3 or S330 only will benefit from such high end opamp i think. And also the price....big nono! hahaha

what do u think about AD8066? u making me very hard life now, need to suffer on choosing the right one to pair... but thats the fun of it LM4562, i was told told that that opamp's sound signature is abit u-shaped (stronger on bass and treble) whereas AD8066 is more flat, more on clarity and soundstage with balance bass...

haih looks like i got to tembak an opamp. have u use the opamps u mention before? can describe the sound signature ah?

the stock cap is 100uf 16V, what should i uprade it to?

all the opamp never use before...since i'm the newbie in audio...
i juz read a lot of review on these opamp...
so the recommendation given is multi-choice, since i onli group them in their sound signature....
AD8066, i saw it before(may be on some head amp), but dun remember where...
juz found some review that may help u compare them:
http://www.diyaudio.com/forums/showthread.php?threadid=90827
seem like AD8066 will be better since there is nearly same price between them..
since the caps may involve in a high pass filter, it will be recommend that use same value caps to change it...
nichicon KZ will be a good choice since it has a good performance near to Blackgate with lower price...
but the problem is difficult to get it...
100uf may leads a "good" price too...

does sound card affect how nice my songs & how solid my bass is?

definitely yes...

It's funny, i tried switching back to onboard yesterday, the lower range has the biggest difference, the bass is like muddy, not accurate, the vocal is not that bright and lacking in details.

what sound card do u suggest for s330? cheap nice & cunn wan..

for me, the biggest difference is onboard giv the sound like 2D while the sound card bring a 3D sound....


use in desktop or laptop?
for music la...
i think xonar u1 may suit u bcoz it is lowest price sound card for music that i can found..
although it is external 1, but it may perform better since there is lesser EMI effect for external sound card...
or u can go prodigy HD2 for RM400, xonar STX for RM600, since music stuff will not drop price seriously as other computer stuff...
hard modded x-fi may be a good choice too...
for gaming....
creative X-fi series(oem) may suit u...
or juz go to xonar D2...

desktop, i think my soundcard & graphic card is like freaking old edi.... probably.. 7-10 years old...
i'm actually a mix of everything.. music, game, & movies.. so which one is suitable for me?

I will be getting the AD8066 for now, and Panasonic FM 470uF for power cap on the soundcard... The Nichicon KZ or Blackgate will be for the speaker ;p

What soldering iron u think i should get? now i'm using some China brand 25W solder, i practiced on some old circuit board...its damn hard to melt the solder and the tip was too big...i think i need to get a very sharp tip one for the opamp change, any recommendation? i heard that for opamp soldering need very sharp tip soldering iron with at least 75W.... which is the cheapest yet most effictive? haha



either xonar U1 or xonar D2, x-fi doesnt sound great if its OEM plus not modded. Both the xonar sound quality is better than xfi. Even so, if your sound card is 7-10 years old, any recent soundcard even the x-fi will be much better than your previous one ; ) Also, some Xonars are PCIE slot, if your mobo is doesnt have a PCIE u cant use them...

Since it's desktop, i think don't get Xonar U1 coz it's for lappy users.

i think only for higher S series only will seperate the bass and SW.(s530d, s730d)
for C3, there only having SW and treble..
hehe..coz i'm having one c3 too

xonar d2?
can handle most of the ur demands....
