Tube vs. Solid State Phono Stage

So, I've always had toob amplification; mostly SET. Upstream, I have analog vinyl only. In keeping with my philosophy, point of view, style, whatever you want to call it, I've felt compelled to go with an all tube phono stage:
Cary PH302.

In summary, this has 55db gain, tubed rectification, RIAA equalization and gain stages.

I have no complaints.

However, I can't help notice that some, what seem to gennerally be considered, as world class phonoo stages are solid state.

In my price range, I'm at least thinking about what a Pass Xono would add to my system.

Any insight or opinions?
