Looking at Phono Preamps

I currently use a Simaudio Moon 310LP preamp, for a Rega P8 with a Hana ML cart. I've been recommended an Octave EQ2 or a pricer Lab12 Melto2 as good partners for my table and cart.  I don't have any experience with either preamp and was wondering what peoples take were on recommendations.  Thanks for your input.
