Yes, I do have some knowledge, experience on the subject. While not the lowest output MC cartridge, .48 mV output is pretty low, and the likelihood hood of hiss will creep into your listening pleasure. I use cartridges typically around .2 mV and there is no quiet tube phono stage out there, period. If the hiss doesn't bother you, fine. But I don't hear any advantage of a tube preamp over a solid-state phono. For the most part, a solid-state phono preamp will be operating in the most linear part of the output of a transistor; class A if you will, and dead quiet. Makes for more detail, a clearer soundstage, all the audiophile buzz words that could apply to better sound.
