A/B-testing D/A-converters - how?

[zongkong]

I'm about to write a thesis on the (eventual) differences in certain qualities between two D/A-converters
(an M-Audio USB Audiophile and an Apogee Rosetta 200 - to be honest I take it for granted that there will be a noticeable difference in a lot of areas. Then again, I've never done a proper A/B-test with converters, so I really can't say I know for sure.).

Now, in order to do this, I'll do some listening tests of the double blind type
(i.e. for every quality tested, the participant has to listen to 3 soundclips - one A, one B, and one double of either A or B. The participant will not know there is a double, or even that they are listening to different converters).

But - I've come upon a problem, since I don't know of any A/B-ing software which can let me use more than one audio driver.

Do you know of such a program? Or do you perhaps know anyone who would be up to creating one for tests like these?

I already know about pcabx.com, however none of those programs let's the user do this.


Many thanks!



This is how I plan to hook things up btw:

For the Rosetta 200:
A/B-program -> Fireface ADAT out -> Rosetta 200 ADAT in -> Rosetta 200 Bal. out -> Monitor mixer -> Speakers

For the USB Audiophile:
A/B-progam -> Fireface SP/DIF out -> USB AP SP/DIF in -> USB AP RCA out ->
Monitor mixer -> Speakers
