My advice is to spend time looking at the measurements of each device on your list, as well as doing some other reading on ASR. (e.g., the
audibility thresholds thread is a great one.) You'll see that not only are the measurements excellent for each one of these devices, but also that they far exceed what's necessary for a well-engineered, transparent DAC. In other words, you should probably put more emphasis on things like price, features, build quality, etc.
From a pure value perspective I'd easily give the nod to the Sabaj D5 because it's a DAC
plus headphone amp; the other devices on your list are just DACs. As Amir's measurements show the headphone amp section of the D5 is a little underpowered vs. some of the best dedicated headphone amps (e.g., the Monoprice THX 887) but otherwise excellent. If you use the XLR out on the D5 you should be able to drive the vast majority of headphones.
If you want to compare the D5 to other DAC + amps there are plenty of those that have been reviewed. Amir just reviewed the SMSL M500 MKII, for example:
