This is a pretty open question.
Can you provide details of what you currently have? Speakers? or are you buying everything now?

Phono/preamp/amp chain. One of them tube the others SS. Which one?
Perhaps any one would do if done right. What would be your preference, generally speaking? Let's assume MC cartridge. This move could be permanent or could be the first step on the way to full tube system. I would probably choose the phono.
