I have a NAD C 355bee+Marantz c6003+MA Bronze BR 2 combo.....clear vocal, very good in mid-low and have a punchy and powerfull bass...BUT I still need a more detail and airy midhigh and treble...(PS. the combo is still on runing-in period)....do I need a 'better' speakers (such as MA BX 5) or cd player?? thx
