Is the 990 really plugged into a switched outlet? I'd leave it in an outlet that was always on.
I have both of my preamps..my 990 and my integra 9.9, plugged into switched outlets on Adcom ACE 515 AC power conditioners/switches. I always put the preamps into standby mode with the remote before switching off the power completly to them.
Is there an advantage to leaving those preamps powered up on standby at all times rather then the way I have it?
