Okay well, I just came into some cash and I'm finally ready to pull the trigger on a new DAC/Amp. I've been researching for a bit and I really like the Yulong D100 and the Audio-GD NFB-11 for good options with my AKG Q701. Keep in mind that I'm not factoring price/value into this comparison. Can anyone speak to how these two compare, sound-wise? My research says that the D100 is on the warmer side of neutral and the NFB-11 is very neutral, leaning towards bright with the Sabre DAC. Can anyone speak to how they pair with the Q701? I know the D100 is supposed to be really good with it. I haven't heard much about the NFB-11 pairing tho. Some people have said the 15 is better on paper, with the warmer Wolfson DAC. I'm hoping the 11 isn't a BAD pairing since a neutral DAC will be better if I want to change headphones down the line. Lastly, can anyone speak to which is "better" on paper? The obvious differences are that the NFB-11 has a 32-bit USB port and DSD support, as well as a bunch of filters. The D100 has only two filters, but it has balanced XLR outputs. I think the amps are relatively comparable, but I can't find any hard info on that. Am I overthinking this? Should I just get one and bask in its awesomeness without worrying about the opportunity cost? Or are these in different leagues and I should definitely be getting one over the other? Thanks!
