For the speaker measurements, there is no need to send the measurement system back to get the data. You just send the measurement files and I create the program to load on the dspMusik that comes with the measurement system. Once it is running then you just send back the measurement system if you are keeping the dspMusik after the demo.
Since file based playback is becoming a big part of music systems, this just integrates the PC into the setup. Maybe not for everyone, but that is why there is an A/D converter for analog playback in the dspMusik. No other DAC's are needed with the dspMusik system, so digital is a cleaner path.
Never heard a CD/DVD-A/SACD transport that beats file based playback to date. That is why I build Music Servers.
Good luck!
