Phono Preamp Settings/Question - Help Please

Hello, I'm considering purchasing a Musical Fidelity MX-VYNL phono pre, however I'm having a terrible time figuring out if this unit is compatible with the rest of my system. My cart is a Nagoaka MP-200 (4mv) and I am using a passive preamp into an amplifier with 26db of gain. I've calculated that I need 53.4db of gain to get a full 2v ouput from the preamp. I can't read this spec sheet... usually phono preamps have a list of db step-up settings however I cant find them here.... am I missing something? Not by any means an expert but I know enough that I need to get this right. Likely will be running the balanced outputs.

Thanks for any help/insight!

Thanks for your input and the resource!

So presumably I would use the MC inputs, even though I have a MM cart, which would provide more gain without any loading issues because I can select 47k? Curious what the overload limit spec means.

My amp's sensitivity is 2.24v, however its a 500W amp and I've had plenty of success with 2v out from my dac directly driving my amp. I have kef ls50's which I believe are 85db sensitive.

The input impedance of my power amp is 50kohms so I think that should be okay there given a 1:10 ratio even if the spec isn't listed on the musical fidelity. My passive is a TVC so that wont hurt impedance matching either.
