177db isn't possible but I know what you mean. Glad it is working for you. Keep it cranked to '11'
For those interested 177db would require 14,263,715,295W at 3m away into a 95 db speaker with 10db headroom, according to Crown's amp calculator. If I drop the desired level to 167db you only need 1,426,371,529 to cover the 10db dynamic range.
Funny, I plug in 100db and it comes back with 285W and I get ~230W out of the Denon and I have measured ~100db in my room which is as loud as I can get it. I think the calculator is pretty close, considering the RS meter is most likely off a few db etc.
