Ok, Day 2 of having the two great earphones, ASG-2, and the 1plus2, side by side: things have changed.
The G-2 really grew on me. I stuck with it for some time and I get it. It's rich in the mids and bass, and the treble sparkly. It reminded me a touch of the MG6Pro, a $1k Custom with a single 13mm dynamic driver. Bass punches, mids are lush and very up front, and the treble balanced.
But the 1plus2 grew on me even more. I just don't agree that the soundstages are the same size. I think the 1p2 kills it. It reminds me of my TH900.
In fact, eke, you mentioned that you did a lot of listening through the iPhone. While that is a practical application, I wonder if you shortchanged your experience with 1p2. I tried briefly out of an iPhone, and things changed. The 1p2 is pretty revealing of the source, not at forgiving as the G-2.
That is my conclusion essentially. I went ahead and plugged them up to my Liquid Glass, and boy did the 1plus2 scale remarkably. Liquid vanilla smooth. The G-2 sounded intimate, almost shouty mids, and congested.
Hearing the 1p2 out of the LG prompted me to bust out my TH900. And I have to say the 1p2 definitely holds its own against it. The TH900 has more bass rumble, and lower midrange, but the highs and mids were both so clear and inviting. The 1p2 is a tad brighter making it sound very clear and spacious. And the soundstages were not even that far off from TH900 to 1p2.
I think the 1p2 likes a nice chain behind it, and I think it required well-recorded music. If it has that, then no-brainer for me, the 1p2 is clearly the best. If you listen to a lot of bright music, like I do, or use your earphone out of the iPhone alot, the G-2 is much more forgiving. I like the ASG-2. I like the way it sounds with bright music. I like that it is so forgiving. I am very sure I'll end up with one of my own. But again, same conclusion - if I had to pick one, 1p2 for sure.
I have a silver/gold cable on the way for 1p2. I'll be sure to comment on sonic and ergonomic differences when I get it.
