Sonic differences Rogue Cronus vs. Cronus Magnum?

I have decided to slow down and smell the roses....well not really, but in putting together a 2nd system I have considered many things...and my reaading and thinking has brought up the possibility of the Cronus.

Does anyone have experience with the difference in the two versions? Sorry to say the speakers are not yet set in stome....However I listen mainly to classic "cool" era Jazz and female vocals...Ella, Sarah, Diana, Julia Fordham...etc.

Thanks for any input...
