I ended up paying 360$ for my emotiva because of the shipping and taxes. That is more than twice the price I paid. I kinda regret buying it at such a high price, for one because it hisses slightly along with the pot-meter not tracking well and it pops louder than I like on turn on/off.
Would rather have found a good second hand power amp or something. Or maybe the marantz pm 6005.
OUch, do other people have similar issues? If not perhaps you got a lemon. If you get a receiver or non-headphone amp, beware of the likelyhood of series resistors to the headphone jack. Some headhones have wild impedance curves that sound awful with just a series resistor. You can always hang the HE-500's off the speaker taps as you've done with the Emo
