Thanks Grant, and thanks for the link to the paper, which as it happens I had seen some time ago. As I indicated in my post yesterday, that appears above and was addressed to Ladavid, my experience has been that well recorded, minimally compressed symphonic music tends to have brief peaks in the area of 100 to 105 db at the listening position, which seems nicely consistent with both Lou's comments and with the 80 watt/channel capability of my amp.
Best regards,
