Yes it does. But you'll have to set this in the Audio MIDI program. The same applies to the sampling frequency. The settings shown in the Audio MIDI program are what's used on the RTX (or any other soundcard), no matter what the setting in REW are. You can check this by setting REW to a high sampling rate, and set a low sampling rate in Audio MIDI. You'll observe very low signal levels at frequencies above the Nyquist frequency of the Audio MIDI setting.
Say thank you to Apple for making this so complicated.
Oh, and it would be useful to have indicator LEDs on the RTX that show the sampling rates that are in use. This would help to notice if/when things go wrong because of such software hickups.
I have actually checked that, changing the setting to 24bit just messes the measurement to some very high level harmonics in a sweep. REW just shows 16bit regardless the setting, and the sample rate does not change with setting either.
The REW works fine, it switches sample rate automatically to whatever is sent to it, you can hear the clicking when it switches sample rate. So the problem is REW.
Also I get much higher level power related harmonics when I use a different software. Still playing around with these to see what works.
The group buy closed by the end of April 2017. I am not quite sure what you mean by "invitations".
Another group buy is very unlikely.

I am not sure I understand this. REW does NOT control the sampling rate and bit depth on my Mac. Audio MIDI seems to hog these settings. I confirmed this with a WaveIO board + LED indicators for the different sampling rates. I am more and more moving to Linux, where where these things work much easier.
I also observed slight differences in the noise floor and mains harmonics (when they are a low level) with REW, compared to MATAA. I know what MATAA does (I wrote the code myself, and it's open source, so everyone can take a look). I don't know the details of what REW does. And other software may do even more different things.
I use REW and if you are using the native JAVA drivers REW supports only 16 bit 44.1kHz bit depth and sample rate. I guess if you are able to use the ASIO option it will apparently support other sample rates and bit depths, but I never tried as the JAVA drivers are stable and the defaults are sufficient for room response measurements IMVLE. (I have only ever used it in Win 7 with M-Audio 2496)
Not knowing whether this would be accurate or not under the Mac since it only indicates 16bit.
Black is the RTX and the other is XONAR U7. Seems the noise level of the U7 is lower. But the harmonic distortion of the RTX is lower than the XONAR U7.
I am going to try some other software for the Mac.

Well, REW seems to work with 24 bit on my Mac. ASIO is irrelevant on the Mac. Can you show a screenshot of your Audio MIDI settings?
Also, maybe get in touch with the REW community, I guess they should know more.
The only reason I am trying REW is because it runs on the Mac and is what others are using in this thread. But that little indication on the lower left corner saying 16bit regardless what I select in the Audio Midi setting bugs me, sample rate seems to change fine. I have worked with at least three USB cards and quite familiar with running them on the Mac. Not planning on spending more time with REW until this is fixed.
I have received the analyser yesterday 
Very fast delivery and nice packaging, well protected
Not yet plugged in, I will try during the week end. It is bigger than I expected I have to find a location on my bench... By the way, where did you get the cabinet; I could use the same for my own project ?
Thanks and best regards,
Marc
