Listening to Another Brick in the Wall (FLAC), using the AKG K242HDs, does sound nice, the AKG K242HD have a nice mid range.
Will do more testing in the morning, when I'm more awake.

So far with mine male vocals are a bit recessed, but then again when i got them the entire midrange was laid back, so that could still change.

Which adapter do I need for 2x LME49990MA?

I believe they are both have the same function, but use slightly different PCB designs and they just each use different ways marking the same thing.
I do like they way the first ones are marked (bolder white) better then the second.
The first ones just uses a small white dot to show where pin #1 is.
The second one shows were pins 1,4,5,8 are.
But I'm far from an expert on these.
 
Personally, I would buy the pre-soldered adapters for $18.50 each, off eBay.
Those things are tiny (the LME49990 op-amp itself).
Currently I have 10 LME49990MA op-amps for making 5 adapters and have spent $54 for all parts
and I'm still having problem finding (and buying) a decent work stand to hold them for soldering.

As I understand the first one is single adapter (one sided but 2 in quantity), so they are not go. Second are dual adapters (two sided also 2 in quantity). I'm not going to solder myself, it will be done by electrotechnics store

I can see that now, they used "2x" in both listing, adds to confusion.
Better if the first listing said "2 pieces, single sided".
I had ordered 10 pieces of dual sided adapters that look the same as those single sided ones in the first ad.

I just installed the stx into my rig and WOW, I can hear such a HUGE night and day difference in sound quality as compared to the onboard audio on my asus maximus 4 extreme-z motherboard.
What an awesome product! Really glad I got it.
Still using the default op amps and it seems to work pretty well for me as I'm comfortable with its sound signature.
Might order the other recommended op amps soon to try.
 
All in all, a pretty amazing piece of equipment!

Hey guys I'm kind of having trouble with my Essence ST, I'm trying to set up the RCA output but I'm not getting any sound, my setup is like this, Essence ST > RCA to RCA > M-Stage Amp > HD 650. I've got it set as 2 speakers in the xonar audio center, that is what you have to choose for RCA right? Is there any more settings I should do?

When I bought my used Essence STX, I got zero sound out of it, turned out to be one of the three op-amps (the buffer op-amp) was not seated all the way.
Just had to remove the shield cover and press down on the op-amp to get it full seated.

Thanks for the reply, does it make any difference that the headphone jack works ok? Or would it still need seating? I've been using that aswell as its in-built amp for the time being until I get the M-Stage working. I'll give it a try tomorrow anyway.

The Essence ST (& STX) comes with three op-amps, two are called "I/V" which are used for the headphones, the third one is called "buffer" is used for the RCA outputs.

Hey I opened it up and it looked like nothing needed seating, I installed it back in and it suddenly worked? Not sure what happened, thanks for the help anyways.
Wow big difference in amps, sounds great.
Question would it be worth it getting a better 0.5m RCA-to-RCA cable working between my m-stage and essence st? Would I notice a difference?

I would say no, if its a decent cable (I am talking $20-$30, like QED performance audio) then i dont see a need to go more then that.

Monoprice sells thicker (better shielded) RCA cables for a low price.
Would it make the sound better????
At least it would give you piece of mind.

Hey guys,
 
is the headphone output of the STX valid or ok to connect to an amp? I only ask because I would like to keep Dolby Headphone if I game. I would leave the output ungained at 100 instead of switching over to the cinch output.

Why do you even need to hook up an external headphone amplifier to the headphone output of the STX?
STX should be able to drive any mainstream headphone on the market.
