Every gains setting post on the internet says to set the tone controls and eq flat and turn the loudness off, when setting gains. This is not the way i listen to my system, so why would i want to set my gains this way. Why not turn the tone controls up full and the loudness on, then set the gain. this would be like a worst case scenario i would think.
Then when you use the loudness control or adjust your tone controls you won't be clipping because the gain was already set with these maxed out.
