If you have a SPL meter (RatShack sells a nice one) you can measure the upper level that you like listen at. Do this by playing some music at what you think is the highest level that you like to listen at. Then without touching the volume dial, put on a test disc with some pink noise or a 1khz tone to determine the db level. You would then make note of where your volume dial is on the reciever.
