KOETSU VERMILION and audio research PH7

HelloI would like to get a Koetsu Vermilion but I don't know if my phono stage audio research PH7 will do the work due to the 0.2mV. I've got a zyx OMEGA and Ortofon cadenza Black, and for me the 58db of my PH7 is enough,,, so with vermilion ???
Your opinions ?
