   You need RIAA equalisation for a phono preamp. You also don't mention   
   whether you are using a moving magnet, or a moving coil (low output) phono   
   cartridge. MC carts require further amplification, as well as RIAA   
   equalisation.

   **What a load of bollocks. MOSFETs are not specifically capabloe of higher   
   headroom than any other output device. Headroom is, OTOH, directly related   
   to the regulation of the power supply. Well regulated power supply = low   
   headroom and poorly regulated power supply = high headroom.   
      
   BTW: Compare your fancy, shiny new MOSFET amp to a Phase Linear 700b (BJT)   
   sometime. Be prepared to be surprised.
