It is too early as I am a strong believer of breaking even solid state audio equipment in, having heard the A/B difference.
I am also a believer of blind testing as the placebo effect is incredibly strong - at least to my ears and I think I'm a pretty objective person.
So one advantage with the Dragonfly is that one can easily do an objective blind test as the two Dragonfly looks identical. What I did was to mark the bottom of the version 1.2. However, I only look at them from the top with the bottom facing the table. I then scramble the two dacs until I do not know which is which. I listened to them intently last night (just got the 1.2 yesterday). So far, I actually picked the 1.0 as my preferred device to my surprise, though they are very close. There's just more 'grip' and punch in the lower frequencies. I was very surprised because I thought the 1.2 sounded better out of the box. Again, that's the power of suggestion and expectations. I then double checked in the Windows drivers to make sure I had the correct unit marked - I did.
My test unit is the excellent ZMF Modified T50RPs. My HD650 is in the office and I'll get it tomorrow and will report back after a few dozen hours of breaking in the version 1.2. I do hope it will be noticeably better than the 1.0 after an objective test. I will also have my sons listen and evaluate as they have very keen ears.
In short, at this point, I am not hearing much difference if any.
At this point, I can think of four possibilities:
1. I have lead ears that are not good enough to tell the difference. I hope not as I've tested some higher end items and hear a difference. And lower end too.
2. There is very little difference between the 1.0 and 1.2. If so, the $99 is a great value.
3. 1.2 not burned in yet and difference will show after a while.
4. My 1.0 which is in the most recent batch is actually a 1.2 but not labelled as such and to tell a difference, one needs a 1.0 from much earlier production cycle.
Cenacheros, I'd love to have you do the same blind test and let me know if you still hear a significant difference. I'm not challenging you as I am really just interested in an objective blind test, having no personal ego invested in this nor do I have allegiance to any manufacturer or model.
