Hello, am new here and i need your help. Recently i upgrade my cartridge from an ortofon 2m silver to the sumiko amethyst. My problem is that must open up the volume knob to hear good the sound. My phono has 3mv output and the cartridge is 2.5 mv. With the ortofon i wasn't crank up the volume so much. My set up is project the classic turntable, project phono box , and an old 45 watts jvc integrated amp. Thanks
