Having the same problem 4HT, with my brand new 950 that I got on Tuesday. It may be that I don't know what I am doing yet, but it seems funny that I have to adjust the trim to something that is non standard to get the right volume of sound out of it. When the 950 is calibrated using the 950 signal at 0db, the output from my speakers at full volume +10db is around spl 85db. I also have to crank the trim down on the subwoofer to -12 db to keep the house from coming apart.
