@rankaudio "Luxman has failed miserably to provide enough gain compared to the digital inputs"
There are no digital inputs on the SQ-N150 only phono and line.
Do you have the MP500 plugged into the phono input and the source selector set to MM? Is the cartridge wired correctly into the head shell? The phono input on the SQ-N150 is more than sensitive enough for the MP500. Did you read any of the manuals that came with your equipment?
