Suppose I get a tube preamp or integrated amp and I plan to use an external phono stage. Does it make more sense to get a tube phono stage or a solid state? I'm wondering if I'd want to avoid adding tube sound on top of tube sound or if that's a non-issue. I don't know the specific components that will be involved with any of this. Could be Audio Research, Prima Luna, Conrad-Johnson. The primary source in this system would be the turntable, although I'm thinking ahead about that upcoming Music Hall DAC.
