^ Man you are good.  You need to join the digiZoid team.

I wouldn't say no haha. But I live on the other side of the earth almost though ._. 
 
BTW for all your opamp info needs http://www.head-fi.org/t/432749/the-opamp-thread

Can the ZO2 function while charging?  If so, it also run from the battery while doing so?  I ask because I know Li-Ion batteries wear down faster if put under the stress of a constant charge/discharge.
 
anxiously awaiting my ZO2.3 shipment.

It can be used while charging. their is only one button/method of controlling the device. MizMoxie would really be the only person to know for sure how the power is distributed when it's plugged in.

Got these driving the HE-500 today.

With two of my ZO2, I have to really push the cable into the plugs for them to really register the output, I don't know what the problem is but even with the provided cable (the really thin one), it does it from time to time, what problem do you think this is?

Probably a bad jack, Jack...er I mean Grev

I had a similar problem today walking around with my M-80s and the left ear cutting out for a half second but it stopped after a bit. I did notice my ipod headphone jack wriggling around though and I still haven't been able to get anything to cut out intentionally and haven't had any problems since. I pushed all the plugs in tight and it seemed to fix it though.

Typical 3.5mm jacks, like the ones in the ZO, have contacts on only one side.
If the plug is a bit odd sized, or moves, it's real easy for it to break contact.

Do you think I should make a new thread? Since it has changed quite a lot with high and low gain now and the impressions in the first post doesn't reflect the current product anymore. I could also add my impressions to the first post and others as they show up.
 
EDIT: Well it's up http://www.head-fi.org/t/589201/digizoid-zo2-impression-discussion-thread

It's strange, guys, the plug issue happens with my Clip+ but is fine when I have my Ipod line out.

Got the 2.3 today... regarding the output impedance mentioned earlier, I did the best I could - hooked some multi-armature IEMs to the various ZO generations and fired up RMAA. Output impedance of the ZO 2 seems slightly higher than of the ZO 1, but nothing to worry about - basically a bit higher than AMS Sansas, on par with newer Cowons or iDevices. All ZOs were measured at lowest processing level - the ZO 2.1 sure had some issues, as we all know already, but I didn't notice its lowest processing level was already that high.
 

 
In comparison, here's what some really high output impedance looks like: http://rmaa.elektrokrishna.com/Comparisons/32%20Ohm%20Multi-Armature%20-%20Cowon%20J3,%20Sansa%20Clip+,%20Sony%20A845,%20Hifiman%20HM-801/fr.png

Interesting, could you also test low gain (highest vol level in low gain)?
 
BTW there's a new thread for ZO2.3 http://www.head-fi.org/t/589201/digizoid-zo2-3-impression-discussion-thread/

How would you rate the sound improvement over unamped?

The output impedance stays the same, it's not volume dependent.
