Hi Jsd52756, The first thing you need to do is buy the radio shack or some other SPL meter. I prefer the analogue meter.Do this first and then let us know the level when you have it at 1:00 etc. Also all systems sound different when playing at different volumes due to room and speaker/system frequency response etc. The ultimate goal is full range freq response at a natural volume level and then the recording is the limiting factor. Listen to all recordings at the same volume control setting. Some recordings got the dynamics and levels correct, most do not. If you then want to listen to loud or soft recording it is up to the recording, not your volume control.
