I would agree with ehider's comments about the Neo tweeter being world class. It truly is wonderful. Fast, transparent, non fatiguing. They are electrostatic in sound, only better for me. When coupled with the amazing McAlister PP150, bells, chimes, percussion, ring to life in a manner not heard on most systems.
I listen to my Neo's in all sorts of situations, toed in directly to me, or shooting past my head by 15 degrees, or even crossing in front of me. All sounds great, just a different presentation. I do not point them just straight ahead as I listen to them in an equalateral triangle or greater, and that is too far off axis.
With the Neo 2x being a smaller box version of the OB 5s I have, I know the great sound you are hearing. I think that Neo is killer good even though I have not heard it. Ha.
