Hi, I finally bought a pair of Pioneer Hpm 60 and the sound is incredible. I´m looking for a new amp but it´s a hard choice. I would like a Marantz but there are three models I like: 45 w´s 1090, 36 w´s 1070 (the one I prefer) and 30 w´s 1060. Anyway I don´t forget any sansui, Luxman or pioneer for example but I don´t know what´s better for my Hpm. I basically listen Rock music. Thanks
