Why is Sonor so unpopular in the US?  Often getting lost in the Pearl, Tama and DW generation, Sonor is not even considered sometimes.  Yet I GUARANTEE you, that you will not find a better high end drum.  I absolutey love Sonor and when I can afford my Designer Series kit, I am sure I will love it more.  I have played on almost every other major brand and Sonor was the one.  Sonor makes the thickest shells available which allows the drums to connect with deep frequencies that no other company can duplicate.  Listen to Steve Smith or Danny Carey to hear it.  Absolutely incredible Drums.  Try S Class Pro or the Delite Series.  Try them out!
