The Platinum and sonata are not wimps when it comes to ROCK.B.S. they are ony good for classical or acoustic! Theyboth are as neutral as youll get for the price or even higher.The bass on these beats all similar priced ones.Even when I was shopping around mal order I was told these Grados are great rock P.U.s You want a nice classical or acoustic cart? get a Benz gold.r if its rock GO GRADO!!
