Would you call Elear a great value/performance HP?
Hard to say ... there was an active discussion on Head-Fi.org in the AQ NightHawk thread around those cans vs. Utopia (not the Elear, if I recall correctly).
Worth reading, but someone who was listening to both sets with a Violectric V281 felt that 'Hawks were close enough in sound signature that the additional spend seemed insane (and this is a guy whose opinion I trust).
For me, and this was only listening for about an hour, I felt that the Elear + BHA-1 was a noticeable step-up from the NightHawks with the same amp (Audio Perfection had both sets on-hand and I went back and forth with familiar music for about an hour). I liked the combo, but, was more impressed with the BHA-1 than the headphones themselves, from lots of listening with the 'Hawks out of my Lehmann Rhinelander.
I almost bought the BHA-1 on the spot, but the image of my wife looking at me gave me pause...

... we are still fixing up the house and all of my money is going into construction for a while.
