Reran it tonight. Come to find out I had already set my fronts to "small 40hz" as per some recommendations in the Denon 4806 threads (audyssey recommends it, but Denon sets anything under 80hz as large...can be overriden). Anyway, although it had no bearing on analog bypass (fronts set to large) it clearly had a bearing on trying to set up the Servo 15 last night...anything I did above 40hz was meaningless.

Tonight I set both fronts and LFE chanel to 100hz and reEQ'd, then rest my crossovers in the 4806 back to small 40hz (still debating "large', it only pertains to movies) and LFE of 90hz. My only concern now is that even with the Servo's gain set to about 1/3 my volume preset on the SMS-1 is only 9. That's what it takes to get a "flat" reading with the fronts at about 80-82 db. So far it sounds very good. Thx again,
Ted
