There is an article in the September Sterophile by Art Dudley talking about transformer step-up devices for MC cartridges and how to select the optimal gain and loading for your particular cartridge. He discuss a relatively inexpensive unit from K&K Audio in NC (www.kandkaudio.com) that has selectable gain and can be bought either assembled or in kit form. I thought about trying one myself as I use an Aesthetix Rhea unit to provide all the gain for my MC cartridge. The only thing that has kept me from trying this is the requirement of buying another pair of expensive interconnect cables. This might be a good solution for your application.
