Another 'noise' question regarding the MCP600...
Is there any appreciable difference in volume or tone of the emitted sound when running on 12v vs 13.8v? I really liked Cathar's info on the Iwaki RD30 undervolted to 18v but considering the prices I am being quoted would allow me to get 3-4 MCP 600s.....well....till I win the lottery it will be the MCP 600 for me
