First,THESE ARENT MINE! There is a response to a wtb for grado hp-2s by Vitali selling them for $300 and another reponse asking for $400. This is in regard to an audiogon wtb ad. Look up the hp-2 on the search and read the responses to the wtbs. SEE THE AD TO SELL AN RS-1 AND GRADO AMP FOR $3450,its entertaining.
