I have the MS2+ and a Yulong D100, and even thought I think the Yulong is better, the MS2+ is no slouch and very good and convenient for the price. I agree the NFB 2 or 3 is probably a better value, you would also have to consider it is not made here, how audio GD backs up there products ( Ive heard mixed opinions on there customer service) and their units are tanks, very bulky etc. I wanted to get a NFB but i am going to wait till Schiit shows their dac plans.
I find my nightstand set up of the MS2+ and E9 with the D7000's to be an amazing set up. I enjoy it almost as much as my main rig. The MS2+ really surprised me how well it sounds. It is the perfect dac for a nightstand rig or a somewhat portable set up.
