I did notice opening things like windows control panel while foobar is playing results in a considerable delay in the window popping up,so does right clicking a track in the playlist and selecting open containing folder,but it did this with the old drivers too,using KS fixes the delay.


Glad I'm not the only one. This isn't a new bug, though. The same thing happens when I run ASIO with the previous set of drivers, the whole system gets lagged; it takes around 1 minute for Miranda (IM client) to forward URLs I click to my default browser, folders take a long time to open as well, and sometimes the whole task bar will just freeze.
 
With the new set (beta) I also had a major problem with the microphone, it just sends really loud static. I couldn't figure out what was causing it, so I rolled back.

Well! *sticks nose in the air* I've just ordered samples of the LT1057CN8 to swap out the 49860s.  Who's the awesome chip rolling cat?
 
Me. That's who.  :"P

Some people seem to forget their headphones or circuits also play a part and suggesting the LME don't produce any low bass is quite incorrect and just shows a lack of experience.
You are on the right track though, keep testing until you find the units that are right for you.

I noticed that using lilith player has none of these problems, so it may be foobar problem.

This is true Deep bass is being reproduced in that i can play back a 30 hz tone with plenty of volume (real instruments rarely go down that low anyhow), it's just the leading edge of things like bass cello plucks that are missing.
 
 
On another note (har har) i called Asus and asked them the questions i had posted earlier. The ST with a H6 *will* produce 8 full-range channels. There is no low-pass filter on the "subwoofer" channel.  Also, unfortunatly the clock on the ST does *not* effect the H6 in anyway. The person i was talking to did not understand my questions (as usually happens when i talk to a tech support person) but they were relaying to the "audio guys".  Things may have gotten screwed up between there and her end. I'm a little surprised that the H6 is not effected. That means that the channels are being re-clocked rather than the whole stream at once?

Well perhaps they didn't understand your question.  There is no clocking circuitry on the H6 at all.  All the clocking signals come from the main card. 
The ST uses a normal XO but also has a seperate chip that cleans the timing further.  So if the timing on the main card is higher precision, I cannot see why it wouldn't be on the H6 aswell, if you follow the logic here.  I have both the ST and H6 cards, just had a look at them to verify there is no timing circuit on the H6 at all.  Just DAC's opamps and caps.
No there is no lowpass filter on the card...it is tunable through software crossover.  There is also a seperate volume for each output if that helps you at all.

then you'll be seriously addicted, opamps rolling is a very hard drug..as you'll find out soon enough

As an audiophile i appreciate the fact that i don't have to spend thousands of dollars on cables that "remove resonance from the signal", little stones that "correct magnetic fields" or other such nonsense.  These op-amps really *do* make a difference, and so far the cost is free and it might get to a couple of bucks if i really get into it.

Yeah, i'm betting they didn't. Thanks, that's all very useful information.
 
By the way, what i hope to set up is a good ambisonics system in time. That's why the 8 full range channels were important, as you can make a full sphere with them. 16 is better, but i'm not that crazy yet.

some cables change the sound as much opamps, haha...but apparently trying ADA4627-1B right away will save you a lot of time and money. I've got two of them on my desk, too lazy to solder them atm, LT1363 just hits the spot for me
