Dmailer,
I am familiar with the Mahlers as well as the Beethovens whic I own. VA and Sumiko both recommend wide placement; their rule of thumb is about 70% of your room's width. My friend who owns the Mahlers has about 11 feet spacing between the speakers with great results. My Beethovens are about the same as yours 9ft, and I sit about 10 ft from tne speakers. and I suspect that they may sound as good or better with wider spacing. BTW you have a great speaker.
