I have done a bit of research on combined DACs with built in headphone amplifiers that plug in to computers via USB. Listening to headphones through a laptop or computer make them an easy upgrade option, are pretty convinient and provide a nice boost in audio quality. I made a list of all the interesting ones that I could find for me but thought it could be useful for others looking to buy as well so here goes, ordered by price...

I also want to try and make a chart to show the features of each one but this will take me a while. Using the one that I currently have as an example: I will put in there all this information:
Yulong D100 mkII

Max Impedance (ohm): 600
Max Sample Rate (USB): 24bit / 96khz
Max Sample Rate (other): 32bit / 192khz
Digital Inputs: Optical, Coaxial, USB, AES / EBU
Headphone out (3.5mm / 6.35mm): No / Yes (x2)
Other Outpus: RCA (unbalanced), XLR (Balanced)
Asynchronous USB?: Yes
Jitter: 1PPm

Any thoughts on models to include (remember just ones that you have heard good things about) or specifications to include for the chart let me know. I will try to get this chart done and uploaded as soon as I can but some of the info is hard to find.
