I previously reported problems with 1.3.9.10 and my Weiss Minerva DAC. Today I installed the OSX 10.8 Firewire driver from Weiss and now 1.3.9.10 and direct mode works just fine.

1.3.9.10 works fine on direct mode with my iMac and B&W MM-1s, however, with my MBP and Weiss Minerva (using Firewire) in direct mode the music is heavily distorted. I went back to 1.3.9.9 and it works fine in direct mode.
