@beetlemania , The "random peaks" I was referring to was in regard to your comment regarding my listening levels. I don’t listen at sustained loud listening levels. Almost never at levels that would occur during live concerts. I scale down to room size. I do have a fairly generous sized room, and power accordingly.
I drive Thiel CS 3.5’s which don’t drop below 4 Ohms. The suggested minimum power levels I previously posted are not something I made up. Those are the minimum power levels Jim Thiel would recommend. For my CS 3.5’s the minimum would be, depending on vintage, between 80 and 100 Watts per channel into 4 Ohms.
The high Wattage numbers posted are a consequence of impedance. I don't think many would think that the comparable minimum 100 Watts per channel into 8 an Ohm load would be excessive. And, often times it's not so much the power output but the low impedance that many amps find difficult.
