my issue is that I have to go to the menu and change the mains to large every time I want to listen to full range 2 channel in bypass. I would imagine if you are running Klipschorn's and LaScala's you have the speakers set at large all of the time. You must have lots of space for those speakers. I know they are the size of a washing machine because I had a pair of LaScala's way back when and I constantly fried the tweeter. Lucky for me there was a speaker repair shop close to me and he would change out the diaphragm for $60 every time. I always wanted a pair of Klipschorn's, they must sound incredible with the Macintosh amps.
