I always thought I would miss preamp tubes if I crossed over to the dark side, but I recently went from an LTA MicroZOTL preamp to Pass XP-20 and have not looked back. Details emerged, stage grew bigger (especially higher), and most importantly for me, my noise floor dropped like a lead balloon. Tubes are great, but you might benefit from considering SS as well (particularly if, like me, you have any electrical gremlins that can be exacerbated by tubes - particularly in the preamp where the signal is of lower amplitude).
