I am nowhere near playing around with balance. I just want something that has superior sounding (no dry~harsh sounding thought) and long lasting battery life with the power to run HD650 and HE-500. I want to make this the last and perhaps best portable setup possible.
IBasso seems like a "steal", but I don't have much knowledge about how it sounds. RSA Mustang sounding really impress me so does the Asgard. I want something quite simlilar to those.
