Which Denon 103?
I use 103R. It is a low output MC cart that has greater phono amplification requirements than many. I use a phono step-up transformer device with it and my ARC pre-amp to enable proper volume with low noise. If you have turn the volume knob up well past 12 o clock to get higher volumes, then this might be a problem. Check your phono pre-amps input sensitivity spec versus cart output spec to see if there is a discrepancy.
