How much gain is needed in a Phono Preamp for a 0.2 to 0.3mv low output moving coil?

I have been out of audio for 25 years and am now getting back into getting a system. I have looked at Manley Chinook, Ear 834p, and Audio research 5, 6, 7 Phono preamps, after reading thru many or post on Audiogon. All have about 57db gain to 60 bd gain. I have been looking at getting either a Dynavector 10x5, Benz micro Silver, Ortofon Quintet Black, or a used Benz Ruby Z (if I can find the money). Is 57db enough gain for the cartridges. I would also welcome feedback on the Phono Preamp. I am leaning toward the ARC PH7 or Manley. Either would be around the same price. I would prefer to stay with tubes. The turntable is a VPI Prime. Any help or opinion would be greatly appreciated.

Battery powered ZYX CPP-1 headamp (pre-preamp) designed for 0,24mV MC cartridges and compete with the finest suts ever made according to Arthur Salvator’s info. It has additional 26db step-up ratio for your MM input to drive LOMC cartridges. This is a very special device! ZYX own input resistors made of cryo purified chrystal copper wire (they use the same in material for their mc coil). The resistor is made by winding the wire to a coil that has no inductance in a special process. No noice and no infuctance at all. With this device all you need for LOMC is just MM stage.

So in addition to regular MM stage +26db with headamp for 0,24 mV MC is enough.

I owm Zyx CPP-1 and never had probs with LOMC.
