some bad news here for X-FI user....

i look for my card very detail 2 days ago and i found a lot of 'G-Luxon' capacitors were used in analogue part of the card, and i just found in HERE and HERE G-Luxon was 'well known' bad cap...

So, X-Fi user please prepare for the SQ degradation coming as time passed by...

EDIT: Jamicon cap too....

this is sad...really sad situation that creative users are being forced to into.

by the way, i'm back on XP now. What a lousy feeling. I'm so familar with Vista and now I'm back with a stone age OS, just to get those little audio details back..

Ya, once you enter Vista you don't wish to go back XP, but what to do, we are so 'degil' on SQ....

I've posted it in HD2 bulk thread

*sigh. I recommend you guys don't look for soundcard if you really into music. A good modern onboard soundcard is good enough, and plug it to external DAC via optical or coax. That is the best way to get the best sound quality

But need to be careful when choosing onboard soundcard, digital/optical out should be perfect bit-matched, but what i saw most of the onboard sound digital signal can alter by using the sound effect/EQ setting,my onboard ALC850 is real example, so i highly doubt that the digital signal are come from ADC instead pure digital bit stream....

I already stated modern, all the HD (read: non AC97 based) onboard are capable of bit perfect output on both digital and analog, unfortunately your ALC850 is not the new HD based one, its still AC97 based codec.

Its simple, just disable everything, on my Analog Device AD1988, I just enable digital out only and disable everything else on the driver control panel. Its quite clean, even cleaner than SB Live! SPDIF out, which just a bunch of hiss

What are you talking about ADC? The suond coming from PC is digital, not analog so it doesn't need to converted. The ADC is for recording analog sound like from your microphone. Looks like you need to read more about how PC sound works

lol...not read your thread clearly...sorry about that...

about your last statement, i want to state that i know how PC sound works, i only misunderstood the digital out of my onboard sound was come from ADC because the EQ/sound effect setting of my soundcard control panel can alter the output, which make me thought the sound is DAC>>ADC>>digital...lol....big misunderstood....

BTW, thanks for your correction...

Cool down both... no war haha

Btw, blessedvillain/coolkwc, did u all try the you pax driver for vista? Or izzit currently there's no any other driver tat can bring back the "loss details" on vista har??

Yap, i tried before, but i think the youpax driver(done by Daniel_K) i installed before only bring back the DTS/Dolby Digital features, i didn't notice any SQ improvement over Creative's driver...

cool, here's my rmaa test. I actually don't know much about rmaa so i need your comment about it. let me know



here's the link to html report

may i know what is this test for??

yea...i love creative

It's for xfi xtrememusic modified with lm4562 opamp. Plus 2200uf cap

thanks for ur test, i have waiting so long...but do u use XP now? since this test was done on Vista, what i saw was the frequency response got ripple after 2kHz, if can, do the test on XP will be good enough....

From ur test i noticed positive results of ur mod, really good, especially the THD and IMD+noise, 0.000X% compare to my 0.1XX%(although we really can't differentiate the THD<1%)...overall ur mod increase the SQ at least in terms of test figure

BTW, ur test results convince me to mod the card...

Added on April 22, 2008, 1:30 amthis is just the objective test for the sound card, from the figure u will know how best your sound card is...but this one only objective test, real world subjective listening might not the same, depends on the taste of user...

sometime this test is use to test
1.whether the sound card achieve the parameter claimed by manufacturer.
2.to know the characteristic of the frequency curve.
3.to compare the sound card.
4.as a tool to know the results of mod.

Just mod it, it'll be fun. There is more than RMAA result awaits....

yo...using mod driver or official driver?

Which One Better

Now Downloading Modded One..Haven Try Yet!

You try and see...no try no gain...
