I have a PrimaLuna Dialogue Premium HP, too. So first thing is you don’t need to spend the $ on a phono preamp with balanced outs because there are no balanced inputs on the PrimaLuna. Since you don’t want to spend a lot of $, I think the bottom of the picks would be the Schiit Mani. Next might be a Simaudio 110LPv2. Other ideas include a used Pass Labs. Not knowing the actual budget, the options are many. But I have owned phono preamps from all of the above companies and have been pleased.
