Thank you again for replying!
Yes the 3 op-amps in the ST/STX card handles the front 2 channels. The H6 handles rear, sub/center and sides.
And absolutely correct that
Some op-amps do not like working on some PCBs
Some op-amps do not work well with other (different) op-amps on the same PCB.
If i don't find an answer for the Burson HDs i will definately try the 4986NAs (3 of them).

The LME49860NA (dual channel, DIP-8) are sold on eBay, Around $17 for the 4 piece order.
No one on eBay sells them in threes.

Hi!
I wanted to buy the 10x offer because i need 9 of them as we already said.
But finally i bought:
 
4  LME49860NAs
4  LME49720NAs (for buffers mainly and/or other combinations)
2  OPA2228s (for I/V)
2  OPA2137S (for I/V)
2  AD8620AR (for I/V) pre-mounted
2  LT1364       (for I/V and/or buffer )
1  LM6172
1  OPA2107    and
1  OPA1612    (it is an excellent quality opamp from every aspect)
 
I am also very happy because yes we can put in the I/V section for the sub/center (on the H6 card) different opamps!
So when the ''babies'' arrive i will try some said to be ''good'' combinations and i will share my experience.

The LM4652, LME49720NA & LME49860NA are the same op-amp.
The LME49860NAs are the cherry picks (better voltage range) of the LME49720NAs.
So might as well just order 8 LME49860NAs

I know that but their sound signature is said to be a little different and i wanted to try the famous (specially 2 years ago) 3 LME49720NA combination although i agree with you the 3 49860 will be better. And as i said i already bought them all..
Also i don't know why, i have this strange premonition that the 3 49860 will be finally the most balanced combination. Very strange.

I just ordered 3 of these, when I test them out I'll let you all know how they perform.

Excellent!! I can't wait to hear your opinion for them!

I ordered all the parts to build 3 SOIC to DIP-8 adapters using the LME49990, with the extra I going to need for the build.
Would have been better just to order the three pre-builts from that same eBay seller.

I’m considering the xonar essence for my computer.
So i find this is the right tread for posting this.
But I’m a little bit confused whit the headphone out spec. On some of the reviews i read they state that the SNR for the headphone out is 110db on some it is 117db. The third option I’ve seen is 117db (600ohms).
On the rightmark benchmarks ive seen the SNR of the headphone out is always measured at 111db.
Does this mean that you actually get 117db snr only when the card is set to very high gain??

The SNR depends on the output level, the higher it is, the better the signal to noise ratio. The tests were probably performed at different output levels, among other potential problems. If by "rightmark benchmarks" you mean RMAA with a simple loopback cable, then those are limited by the 2 Vrms maximum line input level of the card.
But what ultimately matters is whether the noise floor is high enough (in absolute terms, regardless of the signal level) to be potentially audible with your headphones.

I wouldn't bother with that, as the noise level is low enough for you to never be able to hear it, regardless of gain setting, volume or headphones you're using.

A few minutes before posting this I went to get a glass of ice water, and as always I hit the 'Lock' button before leaving my computer.
Instead of hearing the lovely Windows 7 'doo-dum', I heard 'doo-KZZARZTbeeeeeee'. Unlocking my screen caused the 'eeeee' to stop,
and after it did it left my ears feeling funny because it was so loud. This was with my headphones off lying on my desk, and now I'm
rather afraid to put them back on. o~o;
 
I've read complaints about this before, but I never really looked into it because I thought it was only a problem with the STX. I have an ST.
I got it on the 14th of last December and haven't had this problem before. Is there any sort of solution for this or should I never put my headphones on again?

If there is, I wish I knew what it was.

It has to be the stupid power saving features built into windows 7, sometimes it provides way too much power to the pci-e slots. Just turn that off and it should never happen.

I just turned it off. ST is a PCI card. I hope the feature's just mislabeled and it actually helps...
 
In case someone doesn't know how to:
Control Panel > System and Security > Change when the computer sleeps > Change advanced power settings > PCI Express.

Okay, I installed the 3 sets of the LME49990. My verdict is its UNDENIABLY THE BEST OP-AMPS EVER! The bass is amped up to new heights, but the music is even more clear. The detail is amazing. Only thing is DO NOT USE THE SAME VOLUME LEVELS YOU ARE USED TO. If you do it will blast your ears off. The guy I bought them off of on ebay did an amazing job.
