MBL has three lines of digital gear- basic, noble, and reference. I had the noble line (1511D/1521) for two years and liked it a lot. Then I received the 1611E/1621 which is overall much better. There is no doubt - MBL does great products, very musical and is a good source to live with. However, in this price range, there're other excellent options like the EMM Labs, DCS. MBL is comparable with these top notch gears. I personally ended up liking the DCS better. I think you should listen and decide for your self.
