@chakster , You forgot the Win Labs cartridge. I owned one. It was awful.
Strain gauge cartridges are essentially resistors that change their impedance with vibration. They require a voltage source and then circuitry to remove the biasing voltage. So they require a special totally different type of phono stage which is included in the price. If the Soundsmith Strain Gauge cartridge is really good it does represent a good value as you do not need to buy a separate phono stage. I will hopefully find out on December 3rd assuming somebody is still at Soundsmith and they are not all at the show.
