No, the STX and the ST have a few variations in design. The clocking circuit and the Pin Header are avialable on the ST only.

right.. and that clocking circuit makes any significant difference at all?

forget the PCI/PCI-E issue and forget the H6 card.. shoud I still wait for the ST release or should I go for the STX.. what are the true differences?

I would say wait and see what people have to say about the ST. You can make up your mind based on information and reviews of both products.

I am so desperate about getting a sound card
I wanted to get a STX , but the improved design of ST makes me hesistate
Wonder when it will actually comes out
Can't wait

If you can wait this long then this ST is worth the wait

..depending on the price, because audio jitter is not audible : http://www.head-fi.org/forums/f46/ji...amples-424172/

hearing a diff between the ST and STX in a DBT/ABX is prolly next to impossible

anyway, it'd be great if it were actually available in shops before xmas.

and despite Asus promises a month ago, there's still no automatic bit-perfect drivers available.

STX is not bit perfect? The jitter test is quite....how do I put it....different from one setup to another, since different setup have differennt jitter to begin with

hah, so you're saying that you can actually hear differences between these samples

the worst of these samples has 100ns of jitter, more than you will EVER encounter in real world applications.

STX has a fixed samplerate, so whether you listen to CDDA/DVD/DVD-A...you have to change it manually in the drivers to avoid any SRC, it's so darn annoying! I always forget to put it back to 44.1 after playing a 48KHz movie

and they even resample KS and ASIO in the same fashion

even the X-Fi cards leave ASIO/KS bit-perfect, but not Asus...it's been pointed out by this russian website 13 months ago : Universal Soldier: ASUS Xonar D2 PM Sound Card Review (page 8) - X-bit labs

Quote:
The Xonar D2 provides full support for ASIO 2.0 with 16-bit and 24-bit data precision and frequencies of 44.1, 48, 96 and 192kHz. [...] The card doesn’t adjust the frequency automatically. If the frequency differs from the base one, the signal is recalculated using a high-quality software resampling algorithm. For comparison, the Creative X-Fi begins to switch the generator’s frequency in this case, clicking with the relay.
and that was 1 year ago, I'm dubious about this ever changing tbh...

I didnt thought to be a Creative fanboy, but I think they`re still the one in the PC audio thing,..
Where are you Obbo...

oh look, it's Mr Sarcasm!

well I could have added M-Audio/Auzentech/Lynx/RME/Edirol/Emu.....even Creative for Christ Sake's...but not Asus

resampling ASIO/KS is a big no-no...the card should set its master samplerate to match the source file and disable ANY post-processing/resampling...again, even Creative does it!

but I'm anyway....Asus promised to update their drivers w/ automatic samplerate, we'll see if their statement will be followed by actions! before xmas if any possible

Currently, the Xonar cards provide bit perfect but you have to change sample rate maually.

As for the jitter tests, Your exactly right. The tests are useless because if you play the sample using the same card you get the same amount of jitter added from the card...DAC...whatever added to the tests samples.

for those wondering, here's the added jitter in these samples :

Quote:
Track 1 - 30ns
Track 2 - 0ns
Track 3 - 10ns
Track 4 - 100ns
Track 5 - 10ns
so compare #2 and #4, are they night and day to you? you will NEVER get 100ns of jitter IRL....of course your own gear will add jitter on top of it, but if you can't identify #2 against #4 in DBT...let's just say that you shouldn't worry so much about teh evil jitter from outer space.

just as a reminder : "A nanosecond (ns or nsec) is one billionth (10-9) of a second"....when your brain will be able to hear a billionth of a second jitter, you most likely will be half human/half machine

If I'm not going to use the multi channel card anyway, should I just go for a STX?
