I have available a pair of HiFiMan HE-300 that are LNIB. They are the latest version. Velour pads.\n Also have a Meier Corda Aria amp\/dac. It is in excellent\/like new condition.\n \n Would trade either for a Grado RA-1.\n \n Would also trade both for a portable or home amp. Nothing in particular in mind so please feel free to send offers. Prefer even trade but will do +\/- cash for the right deal! Thanks for looking.
