Roman,

 

I can't follow most of your arguments. There are many ways to do things and to lay out the architecture of a system. This line/phono combo was designed to work together and to the given requirements. 75-85 db of gain ? Remember this was speced for MM sensitivity. That kind of gain would be way to much. Most preamps and systems have too much gain. Even for MC I consider 85dB gain a bad idea, with a typical MC cartridge with 0,5mV output that would give almost 9V output ! That's about 20dB more than a sensibly designed power amp needs to be driven to full power. With sensitive speakers you hardly drive your power amps to full power. I design systems with as much *headroom* as possible but with as little *gain* as needed. Otherwise all this precious gain needs to be destroyed in a volume control.

Best regards

Thomas
