i've got pass aleph one with b&w 804, and i've heard classe too, but for me classe is too smooth , i think you will be deseapointed after few weeks, because they played always the same thing , you can heard different music, and time after time it's always the same bass or treeble , but if you like tube amplifier with deep bass and thrue voice , buy pass lab
sorry fo my poor english
let me know what choice you will get
