You will hardly find anyone here with a serious rig who has solid state phono stage. Go with tubes, just make sure it is electrically matched with your preamp. I don't know what's available with two inputs within your price range, including used. But if you decide on solid state, check Sutherland 20/20 for $2400 new. But one input, I think. You never see Sutherland phono used. Why is that ? They sell enough.
