Hi SY

i think that the numeric comparision is the mother of all test.

I did... and when i have compared individually (bit @ bit with C++) the audio stream this is my results :

(Same audio source for all the S.O. (rip from commercial CD) )

incoming data stream -> (XP) -> outcoming data stream
incoming data stream = 100 % @ outcoming data stream

incoming data stream -> (Win7) -> outcoming data stream
incoming data stream = 100 % @ outcoming data stream

these are the mathematical results.
For example, if the number 1258 passes through the engine of Windows XP and its output is still the number 1258...all the differences you hear are ...personal

EDIT
I did the test with external loopback, but here the result are biased because the audio stream passes from the internal DSP on sound card, so it's a inefficient test.

PS
since i have wrote the real-time (sound card input) FFT to steal data...and...just for fun ... http://www.bonisaudio.com/Bonis_Free/ago1.zip

Matthias has responded to my query; I agree, he's VERY competent.
One issue is that you used to be able to switch the RME from 'win' mode to 'mac' mode by double-tapping the rotary encoder, but with the latest firmware update (IIRC 1.17) that seems to no longer work that way.

WIN XP SP3 on one of those mini-boxes. I suspect indeed that there's an ASIO issue, but RME installs it's own ASIO drivers so that *should* be correct.

/OT I organised for tonight an AES evening about industrial IP with a patent lawyer who specialises in audio, is also an audio-nut. Should be interesting.

Yeah, I don't think that, properly set up, there's going to be any sonic or measurement differences, the key is being able to get XP to give me that "1258" instead of something else that it *thinks* I want. What's probably simple and intuitive to you is totally arcane to me! 7 (and to a lesser extent Vista) made it easy for me to get the 1258 to come out, rather than MXXLVIII.

Agreed, but this is not the issue of the discussion. And, of course, there's always the latency, and jitter, and... and....

Hi Jan that sound card looks really good
The best I have seen around
I have the Audiophile 192 PCI and no mather what 50 Hz noise floor is at around -80 dB and the res barely goes to -100


Price is out my budget for the use I have for it (mostly building circuits out of Linear Audio) but as I said I have never seen one so good and I have been looking for a while

Well I found out (nudget by jcx) that I was not really testing the hardware but only the software.

In fact, I've been fighting with it for several days now, and talking to one of the designers, to get it work with Virtins or ARTA.
Just today I finally had the RME ASIO test tool working, but the measurement software still doesn't see it...

Send it to me and I'll get it to work. And give it back to you... sometime or other, no promises.
