|#1 I've heard some mention that the XLR outputs use cheap opamps and are inferior to the RCA outputs. What's the consensus on this?|
#2 What's up with the little metal plate that can be unscrewed from the back panel to allow a switch to be moved to the "custom" mode position as opposed to "standard" mode? The manual says that flipping the switch can cause system damage. I use a McIntosh MA-6900 integrated amplifier and Vandersteen 3A speakers.
