MOTU 2408 mk2 worked great when I bought it. Then I upgraded my CPU. At that point it wouldn't work at all. MOTU actually expected me to ship them my whole PC at my expense for 3 to 5 weeks so they could figure out why. That is completely unacceptable to me. Thats when I bought my RME. Never a soundcard problem EVER for about 2 1/2 years now. 6 months ago I got a whole new system again, and now the MOTU installs properly. IF you get a MOTU and it installs properly, they are reliable. If not, the will be the biggest headache you have ever had.
