Gain is in a way a chain, even from Preamp to Amp is important or how easy your amps can drive your speakers... but generally a Phono Stage with 58-64dB will be right.
Don't be fooled from excessive high Phono gain, most do not sound good at a level of >70dB, good Phonostage Design is a real task, even today.
