Just received my MOTU Track 16 and it sounds amazing. Had a little hiccup in that I did not do a fresh restart and power up after installing all the drivers and software that came with MOTU. There was a bit of noise that I was hearing when I used the Mac Book Pro. That has gone completely away after doing a restart and powering up the MOTU Track 16. I have let a few friends hear it and they actually thought it sounder better than the others out there that look a little like the same. One even compared the sound to the Ensemble. I am able to use the Firewire on both my Mac Book Pro and Mac Pro running Pro Tools 9.0.6 with no issues. I am very happy with the MOTU Track 16 it sounds great and is working rock solid. I like how the Cue Mix software works and can see using this live as well. The DSP works great and "0" LATENCY with reverb and eq on. The Mic pres sounded good I used them with a DPA 4099G mic, Shure KSM 141 and CAD Triton Tube. all sounded good and warm with my use which is a Flamenco Guitar. The Led's are bright and easy to see even not close to Track 16. If you need a small unit that has the ability to be expandable like with MOTU 8 Mic Pre (light pipe) and need more than 2 channels this is worth a close look. The folks at MOTU make rock solid drivers, software and hardware. This unit Rocks Thanks MOTU.
