I will give you an idea to audition MM/MC phono stage designed by Allen Wright. First 4 versions were actually not cheap and you can read review here, but the latest two versions are cheaper. Allen Wright is no longer with us, but his partner J.Rasmussen is responsible for the latest versions of this beautifull phono stage.
" The name denotes that this is a Solid State device using something that is called Diamond Transistor Theory, rarely used on High-End Audio products. The most simple and linear audio voltage amplification device is a Vacuum Triode which consists of three electrodes only. They are the Grid (input), Cathode (grounding) and Anode (output). On the other hand, the Solid State Transistor is a current device but is nowhere near as linear as the Triode. It consists of Base (input), Emitter (grounding) and Collector (output). The idea behind a Diamond Transistor is actually a composite circuit that emulates the near perfect and linear Transistor as a current device with the same three electrodes in the circuit then becomes the equivalent of the Base, Emitter and Collector followed by a Unity Gain Buffer."

features:
-Inputs for both Moving Coil and Moving Magnet cartridges
-Load Sockets (for RCA plug resistors) to Optimise Cartridge Performance
-Two Gain Levels, marked MC (Moving Coil) and MM (Moving Magnet)
