I bought an undec NW-2 as my first BLI purchase. It sounds great but the gear noise is almost as loud as the sound unit. The only thing I did was max the volume and reset the speed. It comes set up for slow acceleration but can be easily changed making it better for switching. The only major drawback to me was that the undec came completely assembled. The windows were glued in. I am going to try micro-mask on them. AF Niederer
