My previous amp was the 10W/Ch Shindo Cortese which had no problem driving the Silverbacks in a 25X15 space opening to the kitchen and a hallway. I have the attenuators on the Sinhonias set at 12 O'clock (1/2 power) and have no issues with SPL for 2 channel or HT.
If you're concerned about power, I suggest taking a look at Shindo's new high power (80W) Corton-Charlemagne mono amps. Lashing the Cortons to your 90db efficient Silverbacks should cure any SPL worries ;-)
Best,
Wayne
