Hello 975 destroyer! I was comparing my previous 990 to the 976. I didn't use any other pre-pro in the last 10 years.

The 0-100 or dB value displayed by the volume control is just a relative value that the manufacturer gave to the processor. This is no different than the good old days when the volume merily went from 0 to 10 lol! One preamp would reach a given loudness with the volume at 4, another preamp would need its volume to be placed at 7 to be as loud. That doesn't prevent both of them to go as loud in the end.

Thanks for the comments about my setup!
