Hey HEY!!! Ive heard someone ask this question sometime in my life but at the time it had no relevence to me at the time. I had never thought about it till now... ...on my receiver (Kenwood VR-2080) I have my levels set allmost all the way up. The range is +/-10db. Except my sub and center, the levels are approximatly +9db. The center is +10. I like to have the senter up just an eeeenssy weeennssy bit. Anyway, if I were to turn them down, a tad or at flat 0db, then turn the Master volume up, would there be a difference? I would asume no. I say that because I dont know if there is a difference between level and volume. (other than the fact to compensate for positioning, size of speaker, etc.) Any info would be greatly appreciated.
