Not sure if using a low-end MC is worth all the connections and lossy wiring over a good MM. Especially in your setup. Compare an Audio Technica VM760 with the MC configuration.
How to choose step up transformers?
I just get into vinyl. I bought a Sony PS2250 turntable and I have a Luxkit a3300 preamp. The preamp has a MM phono stage but not MC. I would like to get a MC cartridge so I am looking to buy a Step up transformer. I don’t know what MC cartridge I am going to get yet. Do I need to match up the cartridge and the SUT? If yes, what do I need to match? Likely I will buy something not too expensive such as the Denon DL301.
