1) Does it support mic in (ADC) ? I really need that functionality, although I do have a crap USB soundcard with a mic in right now, I'd prefer not to to have to switch between the 2.
2) How many mW to W can the D1 be adjusted from?
3) Would it totally bring my Denon AH-D2000's to the next level and sound amazing together (for a beginner on unamped crap USB soundcard with only E3C and UE 5EB as experience)?
D2000 specs:
Impedance: 25 ohms
Sensitivity: 106dB/mW
Largest input: 1,800mW
I have heard some people say the D2000 is easy to drive while others say it needs a lot of mw?
4) In simple terms whats the difference between the D1 vs D2? Price difference?
5) Is it worth waiting out for the D2?
Thanks in advance for helping this beginner!

1: The D1 had 4 inputs: Aux, USB, Optical, Coax. I suspect that the Aux would handle a mike input if it is a 1/8" stereo miniplug, although I have not tried it. It does not have the ability to function as a mixer. I'm not sure what you plan to do with the mike input.
2: The output can be adjusted from 0 to earsplitting. There is no milliwatt specification stated, as it depends on the impedance of the driven phones. The sensitivity of your phones are 106 db/mw, so you should have more than adequate power available to damage your hearing!
3: You should certainly notice a difference using the amp, especially if you use the digital inputs. Whether or not it takes you to another level pretty much depends on your starting point of reference. From a crap soundcard, I would say that you will be very pleased. If you decide to change the opamps to a different combination, you will notice even more improvement. The D1 has great potential for improvements in the sound quality, as you have probably surmised from the D1 thread.
4: The D1 has the ability to separate the DAC from the amplifier, allowing it to be used as a standalone DAC. It also has, as previously mentioned above, aux, coax, usb and optical inputs. The D2 has only usb. Cost difference will probably be about $50-60 dollars, although the price for the D2 has not yet been officially posted. The D2 will probably use the P2 amp architecture, which is more sophisticated than that used in the D1. The consensus of opinion is that the stock P2 sounds better than the stock D1.
5: Whether it is worth waiting depends on your anticipated usage. If you want to use devices with digital outputs, the D1 is the logical choice. If you want a small amp with less input/output flexibility, but still have a USB input, the D2 will probably serve your needs nicely
iBasso has been extremely receptive from inputs from their customers, and have made improvements in the opamps that are installed in the stock units.
Both the D1 and P2, and very likely the upcoming D2 have opamp sockets to allow the users to experiment with different opamps to custom tailor the amps sound to ones personal preference.
