Personally, out of that list, I wouldn´t even consider any other choices than the NFB-2/3 and the NFB-11. If you like a warmer sound, then I would go for the NFB-2/3, and if neutral is your thing, then NFB-11 is by far the best value right now. The Audio-gd website is

That DacMagic (sure) and the Mini-i (not sure, but IIRC it is) are using cheap Wolfson budget chips in a dual mono configuration. I think both are very, very overpriced for what they actually are. Especially the DacMagic is a prime example of western audio gear without real value, that sells on mostly marketing and a fancy chassis IMO. It´s the WM8740 in this list...

The NFB-2/3 are using the Wolfson top of the line WM8741 in a dual mono configuration, it should have a warm and pleasant sound signature (just noticed you have a tube amp so you might be into that kind of sound signature). When it comes to neutral superdetailed sound, the Sabre32 is the market leader right now in mainstream chips. Also by far the most expensive Delta-Sigma type chip currently sold. There´s also DAC output so as far as I know it can be used with the tube amp to smoothen it a bit if you want. But the built-in amplifier section is good too. It´s this chip:
