Stopped buying sound card ages ago.....

Now just use digital out to pass all signal to external DAC

Actually I wonder how much difference can there be by separating the DAC from the electric noise,
and are you connecting to the DAC by optical connection?
Do we need a "decent" sound card to output that optical signal, if that's the case?

一般人指extetnal dac係指usb或firewire connecion
大部分係指雙聲道
小部分解埋5.1

Actually much cheaper than X-Fi

Something like this:

is more than enough.

Yes I'm connecting my external DAC with optical. My laptop has SPDIF and optical output.

If you are only passing through digital signal to your external DAC, you don't really need a good sound card at all, since its function is just passing through signals.

If we are talking about proprietary surround sound encoding like DTS-HD/Dolby TrueHD then it is very tricky and expensive to get certified external DAC.

就咁插落去就可以? (Yes, remove the original, install the new IC on the same slot in the correct orientation)要唔要焊?(Not necessary, depends on which ICs you are getting) 我完全唔識搞呢D

For LME49990, nothing to do if you buy from this seller:
http://www.ebay.com/itm/DUAL-SOI ... hash=item2c743398f3
All you need to do is to remove the cover, change the IC on the socket by fingers just like changing other parts in the PC, no soldering needed.
Just take care not to damage the other parts on the card.

The ic themselves are surface mount, and you need 2 to operate in a pair for 1 slot,
for ASUS STX you need 3 pairs for 3 slots.

Sure you can still enjoy your current card for some days before you have decided to improve it,
but the fact is the original ICs coming with the cards are not really good.

This thread is a detailed discussion about how different ICs are performing:

Ya, that's why I said you can have fun with it for now.
Anyway the difference is obvious enough to distinguish itself from the Realtek and you will know where your money has gone to.

I am not sure with that offer,
if you are not going to solder on your own,
check with the seller to make sure you are getting the soldered IC pair on a mount (Dual LME49990 on one DIP8 mount),

You may just ask if what they are offering is the same, finished product on this page:
http://www.ebay.com/itm/DUAL-SOI ... hash=item2c743398f3

Certainly, you can consider any of the other ICs listed there to try, whether they are suitable it depends on the mount (DIP8 will be fine)
and better to see if someone was using it on Head-Fi link I gave on the previous page.

*Some information if you are not sure about the opamp on ASUS card:
-There are 2 types of ICs basically, Single channel, or Dual channel.
-LME49990 is single channel, that's why you need 2 of them for 1 slot.
-Some other ICs are Dual channel, you just need 1 of them for 1 slot.

For ASUS Xonar Essence STX, there are 3 slots: 1 for Buffer, 2 for Headphone Out
-You will need 1 Dual Channel IC for Buffer slot
-And need 2 SAME TYPE of Dual Channel IC for amplifier circuit
That's the reason you need 3 pieces of Dual Channel IC (or 3 pairs of Single Channel ICs) for the card.

-The Buffer slot affects BOTH LINE-OUT and HEADPHONE-OUT.
-The 2 SAME TYPE IC slots affect only the HEADPHONE-OUT
It means that depending on your configuration, if you use only the Line-out,
you can get just 1 pair of LME49990; if you use also the headphone out, you will need 3 pairs.

As a reminder, with some other Dual-channel ICs, like LME49720NA, as it is Dual-Channel in nature, and is already on DIP8,
you just need 1 of that IC, and without any mount or soldering you can install it on your sound card.

Whenever you are buying an IC for your sound card, here are what you need to check:
-What mount is it having? (Surface mount-->need adapter+soldering; DIP8-->nothing needed, can be installed directly)
-Is it single channel or dual channel?(Single channel-->Need 2 ICs to work as a pair for 1 slot; Dual Channel-->1 piece of IC can work for 1 slot)
-Is it compatible with the card? (Oscillation! Check if someone has this problem with the combination "XXX Sound Card + YYY IC")
-Is the IC having design flaw? (LME497XX/LME498XX are said to be having design flaw that their bass is much supressed, while LME49990 can get rid of this)

I have tried to summarize what I have understood after reading the long thread on Head-Fi, hope it helps.

係我就用2x 49720+49610
官配

我指官方49720datasheet 建議配置的buffer

不過49610 係裝唔到上去

要大搞先得
