1. a tip. for future reference ; cpubenchmark.net is your friend when choosing a processor. your I7 rates avg cpu mark on the benchmark of 6950. i normally recommend preferably a rateing of 10,000 or more for a processor as people are useing lots of cpu intensive plug ins/software often these daya. i like the amount of ram you have and the ssd's. what version of windows ?
2. re reaper. actually reaper is a doddle i find.
are you a new reaper user ?
if your a relatively new user , and not done so already go to reaper.fm THEN on the right hand side youll see VIDEOS.
those 80 odd vids are a goldmine of information.
have you ever watched the reaper vids ? people on the reaps forum are also very helpfull.
3. THE SAMPLE RATE AND BIT DEPTH AND OTHER SETTINGS ARE IN THE REAPER RENDER TO FILE DIALOG. PLEASE POST A PIC OF THE REAPER RENDER TO FILE DIALOG SHOWING YOUR SETTINGS.
IF A MONO FILE TO EXPORT SET TO MONO. IF A STEREO FILE SET TO STEREO.
if its not 44.1/16 bit try setting it to that and now see if the reaper exported mono or stereo 44.1/16 wav imports ok into powertraks and biab.
3. IN REAPER TOP RIGHT HAND SIDE IS A DETAIL LINE UNDER THE EXIT X.
what does it say ??. eg 44.1/24 bit/asio/latency 5 ms etc as an example.
4. re mbox 2. if useing biab i make sure windows settings and my sound device control panel (in your case mbox 2 ) as well as reaper and biab preferences are all set 44.1/16 because biab likes 44.1/16 bit.

for our next discussion google "mbox2 problems" .
many threads bout mbox problems it seems in various daw software. eg
