Interesting that this thread popped up now. I just bought an MA-8900 Integrated and when my dealer was installing it (it is part of a complete upgrade of my entire system), they could not get it to handle the switching to pass through mode (I use it to drive L/R speakers in my surround system). Every time they tried, it would literally lock up and not switch to any input. After hours of trying everything they could think of, they called McIntosh. McIntosh is building me a brand new one and working on a firmware update to deal with the switching issue. My dealer lent me their demo 8900 to use in the meantime and it's working fine. I think all the technology getting stuffed into audio equipment, much like mobile devices and computers, is doing more harm than good.
The good news is that the sound is glorious with my vinyl and digital (both Redbook and Hi-Res) music collection. I'm confident that McIntosh will deliver a perfect replacement that I expect to keep for a long, long time.
