I had the chance to audition the BMB, GMB, and YGB about a week ago. The B and G were both SE. Otherwise similar source and setup all around. I found the differences between the B and G to be less discernable esp. given the price difference. But the YGB was a revelation to my ears. Loved it. So if your needs are just SE, either go for the best value DAC around arguably with the BMB or go big and go home with the Yiggy and never worry about a DAC purchase for a while.
