Primare Pre-30, Bryston Bp-25, Plinius CD LAD

I am going to purchase a solid state pre amp just to test the solid state water. I currently run a tubed pre amp to a Bryston 4BST driving a pair of Sonus Faber Cremona speakers. I have some really nice NOS tubes and love the way it sounds but want to try the solid state world for a while without sinking a ton of money into it. I was thinking about these three pre amps listed above. Anyone have any thoughts or recommendation on which I should consider buying? Thanks in advance for your knoweldgeable responses.
