Do you need a phono pre with more than one input? Do you want to run balanced or single-ended?
I think the Einstein is really wonderful, and if you're in the league of the Boulder, this seems like a good choice.
I had the aesthetix Janus for a while, and auditioned the stand-alone rhea phono stage, which was very very versatile. I loved being able to change loading by remote, and it had plenty of inputs and outputs.
Let me know how you like the boulder.
