Keep in mind that all gains having a certain number of db are not created equal. And that certainly applies with respect to signal-to-noise ratios and consequently to hiss levels.
Although I use the low gain (64 db) version of the Herron VTPH-2 (not 2A) with a 0.5 mv cartridge, Keith Herron advised me when I purchased it that it would also be fine with a 0.3 mv cartridge I was considering at the time. Based on that and based on how quiet my VTPH-2 is I suspect that the high gain version (69 db) of the VTPH-2 (and presumably the VTPH-2A as well) would be fine with a 0.2 mv cartridge. And if you were to give Keith a call I’m sure he would provide accurate advice.
Of course this assumes, as is likely, that your present phono stage is what is primarily responsible for the hiss you are hearing, rather than your preamp.
Good luck. Regards,
