Careful. Doing this may induce eddy currents that will decrease the inductance and increase the resistance of the inductor.
Best to use ferrite as it acts as a low reluctance return path or to call it the old fashioned way, a keeper strap

how would you do it? pictures or diagrams?

Also, has anyone successfully modded the XtremeGamer?

The XG is available right now at the egg for $49.99 AR, which seems like a pretty hot deal.
Check post #195

Gamer can not be modded the exact same way as music, due to differences in the op-amp sockets.

Other differences is that Music has coax digital out, while Gamer has optical digital out.

Thanks for the heads up

I just did some calculations and found that the 220uF cap on the power supply is large enough. It just needs better quality. Now I think that the sound quality gain I noticed by changing the capacitor is due to the Blackgate being a lower distortion capacitor, and is in fact part of the audio signal path. A better recommendation for the capacitor would be a 470uF Blackgate or perhaps even a film capacitor (although it will be very big).

are saying to change the cap of psu of the pc?
in that case,whichone do you recomend us? my psu is using a 430v,dont remenber the brand and model.
can i replace my 430v for 500v or 600v?

i meant the cap on the sound card. it's a 220uF Jamicon. i'm saying that quality of cap matters over quantity of capacitance.

So what is the consequences of using 2200 uF power supply cap ? will effect the card or sound signal?

Hi

Hi,
I've been lurking around these forums for a while now and have now decided to actually join, so hello everyone.

Right, now for me to intrude on this thread. I have an X-Fi Elite Pro (bought when they first came out, without the heatsink) and a two year old pair of Sennhieser HD650's with an Equinox HD650LE cable (3.5-mm mini connector w/ 1/4" adapter) on the way.

I use my X-fi Elite Pro for music, movies, gaming and recording so I would need to do a little more work on it I guess? I have read through this thread and am a little confused so if someone would be kind enough to breakdown exactly what I would need to mod the Elite Pro. (PM if it will keep the thread tidy)
Also, would I plug my Senn's into the breakout box, directly into the souncard or should I invest in a headphone amp for the best quality?

Sorry for such a long first post, I promise this is just a build up of questions that needed venting so you shouldn't see too many of these.

I would appreciate any help you can provide me with.

Goodness me ! That cap is not a part of the analog stage !

I don't have the schematics, but for single-ended circuits, the power supply is always part of the signal path.

mrjojoe: It would be best to use an amp, because the breakout box's internal amp is poor quality.

Thanks for the response cotdt. Sorry for going off topic but what amp would you guys recommend for the X-Fi and HD650 and how does the amp connect to the X-Fi? Also, any updates on hotrodding the Elite Pro?

The amp depends on taste. Gilmore Lite is a good option. You need a 1/8" phone to RCA cable, which is quite common at electronics stores. There have been some that have modded the Elite Pro, but you will have to go back into the thread and find those people. Send them a message and I'm sure they'll be able to answer your questions.

The power section will benefit most of a low ESR cap, but it'll be even be better with both a better AND a higher capacity cap. That specific cap acts as a buffer, and buffers are better when bigger: it'll give you more reserve when needed. Bigger caps have a tiny bit more leakage, but that shouldn't be too big a problem (esp. compared with the original one).

It's not part of the signal path: you're input signal doesn't travel through the power supply. I think you mean the power supply always influences the signal quality?

If you add a power switch to the soundcard, with 2200uF you can turn off the power and the sound card will still work for several minutes! So I would say it's overkill, but nothing is wrong with overkill. Smaller caps will have lower inductance and resistance, which makes the cap a better filter at higher frequencies. There probably will not be any audible difference what value you choose, though. I'm just saying that the Blackgate sounds better because it's a Blackgate, not because the capacitance is larger. Reason is because people are asking questions like "Can I use 2200uF computer-grade capacitors?" I don't think they will create the same difference I heard with the Blackgates.

It's a matter of semantics, I guess. The ground is shared, for example, and hum from the power supply will be hum in your signal, which you will hear.
