the main improvement is from the opamps. but if you're creative, you can still find a way to change the opamps. it just won't be as easy as the mod for the mainstream x-fi cards.

GE however, sounds like it might be one of the more "general purpose" series, rather than audio-grade caps
But i can't seems to find any info on GE

Just read the whole post, dont know if i want to do this or just buy a X-fi Prelude. Gotta due more research on that.

Try change Capacitor at ATX PSU. with better Caps..RubyconZL, Panasonic FC Or blackgate......It will improve sound............

I have try it...using rubycon ZL and Panasonic FC caps....but not all caps...because I don't have all value...

After modification this what i get ....Better separasi at high, mids and better bass....

Before mod...

Remove Caps dan Replacement caps

I'm not interested in this right now,but in the future I plan on getting the Elite Pro for my new pc and taking its analog outs to a speaker amp..Problem is,I have no soldering iron nor any expirience with it,are there people who would mod it for me?

May be it's crazzy ....
using different psu give different sonic sound, also using different caps give different sonic sound.

Why people change caps on x-fi with blackgate if it will give the same sound....

eh ada mas hidayat

guys, i'm having a problem in hi frequency sound after the mod
only heard when i'm playing a movie dvd (not exactly original but ripped close enough )
it's a crackle sound, tested on tokyo drift dvd...

i'm not using ERS paper shielding tho....

They are not in parallel. It is a balanced input circuit that have both a plus & minus input to cancel distortion & increase output for a given input voltage/current. There is a coupling capacitor in both input circuits thus it requires 2 per channel. These can be bypassed but if you do both legs of the input must be bypassed or you will have massive D.C. offset at the output. With both legs of the input bypassed the D.C. offset cancels out.

ah that makes sense. i stand corrected.
post #987 of 2194
When I had modded the card before I had bypassed the wrong capacitors. I bypassed the ones right beside the ones I should have. I now have the proper ones bypassed & oh what a DIFFERENCE. Big time improvements in the bass & dynamics. Midrange is also much clearer throughout the range though on some songs but not all there appears a little glare in the upper mids. Treble is way more defined but not increased in level, there is just more spaciousness & detail combined with smoothness.

The dynamics are killer now, very much like live music. You can get a real gut massage with the bass comes from my speakers now. It sounded compressed before. The bass now is so strong & yet so defined that can give you a headache after a while if your not used to it. Yet it never covers up any of the other parts of the spectrum.

I'm still running stock opamps even.

D.C. offset is a little high but still safe at 180mV

Do you have a Pic, so guys know which caps to bypass?

How will this mod on an XtremeAudio compare to the new Azuntech X-Fi Prelude that should be out soon?

no one has yet heard the Auzentech Prelude, but I have heard that same DAC chip with the same LM4562, and I like it a lot. It is definately the card to get, but I heard it will be expensive and if it is, you might as well go for certain external DACs. Even opamps like the LM4562 lack the slew rate and bandwidth required for true transparent sound.
