Thanks to all of you for answering.
Zoya - I think you misread my question. I way trying to find out if any other manufacturers had had McIntosh's great idea of having multiple switched outputs.
But apparently not since the mentioned ones are on simultaneously. It was out of curiosity more than anything. I feel that being able to switch the individual amps out of the circuit is better than having turn-off amps in parallel on the preamps output. Perhaps it wouldn't matter but you never know what may happen. Anyway, I will check out the McIntosh C2200.
